History of Vaccines Timeline

History of Vaccines Timeline


Although the world’s first vaccine (against smallpox) was developed by the English physician Edward Jenner in 1796, the practice of immunisation goes back to an earlier time in the Eastern world. Drinking snake venom to confer immunity to snake bites and smearing a skin tear with cowpox to gain immunity against smallpox were practiced among the Buddhist monks of the 17th century China.

Since Jenner’s critical discovery and up until the late 1950s, all the vaccines implemented throughout this time span were developed at a fairly slow rate. It was the new scientific discoveries and technologies of the last several decades that led to a more rapid advance in molecular biology, virology and vaccinology.

To overview some of the most relevant vaccination-related facts, we have created this blog post, which also includes the History of Vaccines Timeline - a visual chronology of the main prophylactic vaccines developed since Edward Jenner’s breakthrough.

What are vaccines and how do they work?

A vaccine is a biological substance produced to ensure active acquired immunity to a certain infectious disease. Typically prepared from the causative agent of that disease (the weakened forms of the microbe, its toxins or surface proteins), a vaccine ”trains” our immune system to recognize and destroy the harmful agent and any of its associated microorganisms. The administration of vaccines is called vaccination.

There are two types of vaccines:

  • Prophylactic (preventing and ameliorating the effects of a future infection);
  • Therapeutic (fighting a disease that has already occurred).

Where do the words „vaccine” and „vaccination” come from?

Both terms were coined by Edward Jenner and derived from the name that he used to refer to cowpox, that is Variolae vaccinae (which means „smallpox of the cow” in Latin). Jenner’s terminology first appeared in his 1798’s Inquiry into the Variolae Vaccinae Known as the Cow Pox, a study that documents the protective action of cowpox against smallpox. In 1881, as an homage to Jenner’s work, Louis Pasteur proposed that these two be extended to cover all the new inoculations that were being developed at the time.

How it all began

While serving as a surgeon/apothecary appretince (sometime during the late 1760s), Edward Jenner found out that some of the dairy workers in the rural areas never contracted the often-fatal smallpox disease because they had already caught cowpox, which manifested with milder effects in humans. He thus proceeded to collect pus from a cowpox-infected milkmaid and administer it to an 8-year-old boy.

Six weeks later, Jenner inoculated the boy with smallpox and observed that he didn’t contract the disease. This small victory encouraged the physician to extend his studies, which resulted in a report that proved his vaccine was safe in both children and adults.

Vaccination becomes widespread 

After Jenner’s breakthrough, it was Louis Pasteur that carried the torch and made headway in immunization by introducing vaccines for chicken cholera and anthrax in the 1880s. Due to these advances, vaccination gained attention and became a matter of national prestige, with compulsory vaccination laws being passed in the late 19th century.

During the 20th century, several successful vaccines were introduced (against diphtheria, measles, mumps and rubella), but the major highlight resulted from the development of the polio vaccine (the 1950s) and the eradication of smallpox (1960s – 1970s).

But it wasn't until the Coronavirus pandemic that the role of vaccines became evidently essential and people around the world breathed more easily when the first COVID-19 vaccine was introduced in late 2020.

Top free timeline templates for your business continuity planning

When a crisis or disaster threatens to flip your whole world upside down, it’s hard to know how to respond. Luckily, more and more organizations across the globe are discovering just how important it really is to have a business continuity management system that helps you adapt quickly and keep your business running in times of uncertainty.

If your organization doesn’t have any risk management or contingency plan, the good news is that it’s never too late to start. “Failing to plan is planning to fail,” Benjamin Franklin reportedly said, so any time is a good time to start planning your crisis response. On this page you’ll find guidelines, basic information, but also some useful resources and templates to help you build your organization’s resilience in the face of stress.

What is a business continuity plan and why you should have one

A business continuity plan is a document (or collection of documents) that explains what the organization and the employees are supposed to do in case of disruption. It identifies the major risks that can affect day-to-day operation and establishes clear procedures on how to keep the business running during an emergency – which can range from a global pandemic to more common incidents like flooding after a storm or an internet outage.

After being presented to upper management and other stakeholders to get their agreement, the business continuity plan is communicated to all the employees, but also regularly tested and improved. This continuous review process is part of what is called business continuity management system and, in case of emergency, it’s what makes the difference between a company’s survival and sudden death.

Every organization, big or small, public or private, should have at least a basic contingency plan. No company is completely safe from a disaster, so make sure you are always prepared. Business continuity planning is not a nice-to-have, it’s a must.

Benefits of including a timeline in your contingency plan

When it comes to presenting your business continuity plan to your executives, clients or team, efficiency is key. Nobody wants to be stuck in an endless meeting where you read off a bullet-heavy PowerPoint slide or browse dozens of pages. Time is essential, both in meetings and in disaster recovery. And when plans change, as they often do, you need a quick and easy way to update them.

That is why we recommend creating a timeline or Gantt chart for your presentation, to better illustrate the series of events and your planned response by minute, day or month. Here are three clear benefits of including a timeline when you present your business continuity plan to your stakeholders:

  1. Timelines – especially the ones that feature swimlanes – can effectively portray the different phases, tasks or milestones that make up a process. In the case of business continuity, it can show, on one slide, a snapshot of your plan, with just the right amount of detail.
  2. When you represent it visually, the information included on the timeline is better absorbed by the brain. You need all your stakeholders to understand and agree on the business continuity plan, and a timeline or Gantt chart can help you make your point clear.
  3. You can save hours of work preparing for your meeting, since you only need to create one good slide to present your plan. And if you use a timeline or Gantt chart template like the ones we’re about to show you, it will make your work significantly easier.

3 Best Free Templates for Pharmaceutical Timelines

Medical treatments have evolved a great deal since the time of Hippocrates and Paracelsus. Leeches, bloodletting and potions have given way to an industry strictly controlled by regulatory bodies where only the safest and most effective solutions are accepted.

Breaking ground on a new drug or device takes years of testing and collating immense quantities of data from numerous sources. Not only is planning ahead more important than ever, but the manner of presenting the data to your stakeholders can help you secure that critical funding necessary to keep your projects on track.

Why is a Pharmaceutical timeline useful?

One of the best ways you can organize ideas, measure progress and ensure compliance with regulations is by creating a roadmap. Managed correctly, a timeline for your Pharma project can help you:

  • Evaluate the recruitment of patients for the clinical trials to ensure the proper amount of testing meets the prerequisites of regulatory bodies or if efforts in this direction must be intensified.
  • Determine if the results are on track according to the originally planned research phases of the project.
  • Check deadlines for industry-mandated certifications and patent renewals that allow the legal manufacturing and distribution of medical devices and drugs.

Therefore, given the benefits of using visual representations in the lab and the boardroom, it’s definitely a planning solution worth considering. Start organizing your development process with these powerful and easy to use visuals and you’ll soon see all the pieces of the puzzle falling into place.

How to spend your day when you Work From Home

Among the numerous side effects of the coronavirus outbreak is a change in the way we work, with many of us being required to shift from an office setup to a work-from-home lifestyle. While some companies may use this state of affairs as an opportunity to start building a culture that nurtures more work flexibility, the regular nine-to-five workers might encounter difficulties in getting accustomed to the new circumstances.

Although the idea of remote work seems attractive (performing your tasks in a cozy makeshift quarantine bunker, sweatpants on), the lack of stimulation caused by human interactions can take a toll on our productivity and creativity. So, we created this blog post, which provides a series of recommendations on how to spend a day when working from home to get the best results; you’ll also find a practical work planner to help you transform them into a daily routine. Bonus: at the end, we’ve included insights from the leadership team at Office Timeline, who have been working from home for years and gained some valuable experience they’d like to share.

Tips and tricks for a more effective work-at-home day

1. Start early

Researchers have shown that our brains are most active and ready to get into gears right after we wake up. Furthermore, psychologist specializing in human motivation Rod Friedman argues that the first three hours of our day are the most valuable for maximized productivity. Hence, don’t snooze that alarm clock and don’t prolong your breakfast unnecessarily as that morning sluggishness will seep into your day. Instead, wake up first thing in the morning, put on that pot of coffee and dive into your to-do list (that you prepared the day before) as soon as possible so you can make the best out of those three golden hours. It will fuel your motivation and ensure a steady progress throughout the day.

2. Get prepped as if you’re going to the office

Since you’re working from home, you might be tempted to skip the showering-getting dressed routine (yes, we know, sweatpants are really comfortable). However, that precise routine helps make the transition from your pillow to your computer less jarring and puts you into a more energized state of mind. Plus, practicing this habit will make it easier for you when things return to normal (assuming that life will ever be the same after this lockdown). So, do all the things you would do to prepare for a day at the office because it activates a mental association with the idea of work and can make you more productive.

3. Schedule calls and meetings in the afternoon

Most of us are groggy in the morning and need a bit of time to adjust to the new day ahead. Having recommended that you get ready and started as early as you can, it only makes sense that you shouldn’t distract yourself from focused work with calls that might last longer than expected. So, start with the “solo” tasks in the morning and save the collaborative ones for later – when you’ve officially woken up, your voice is not croaky, and you’re all dressed up for “the official” meetings.

4. Create a work schedule to structure your day

Since we’ve suggested above that you group solitary tasks in the morning and the collaborative work for later, structuring your whole workday will provide further clarity and efficiency in managing your time. Creating a plan of what to do and when to do it over the course of your day will help you stay on track and keep focus. Use online calendars, personal reminders and events or a visual timeline to break up your work and pace yourself in cranking through it.

To help you get started, we’ve used the Office Timeline PowerPoint add-in to design a template for a Work from Home day planner that you can download for free. Seamlessly integrated into PowerPoint, Office Timeline is a lightweight yet powerful timeline maker which lets you easily generate and update accurate schedules. Choose from dozens of smart templates and use the tool’s various functionalities (timeband scale in hours and minutes, task duration, swimlanes) to create customized plans that you can update on the fly when things change. You can build your own work planner with the free version of the app, or explore the Pro edition to produce more complex visuals with swimlanes like this WFH daily schedule:

Work from Home daily schedule


5. Plan your work around the times when you’re most productive

Speaking of well-defined work schedules, an important aspect to consider when planning your to-do list is your productivity pace. It’s natural for your motivation to fluctuate throughout the day, nobody can sprint through their tasks from morning to evening. Thus, pay attention to yourself and identify the ebb and flow of your efficiency so you can capitalize on it and better organize your work timeline around it. Keep the more difficult tasks for your productivity peak and use the slower moments of your day to take care of the easier ones.

6. Use a dedicated workspace

Just because you’re away from your regular office, it doesn’t mean you can’t have one at home. Instead of slouching on the couch or in your bedroom (spaces associated with leisure time), choose a specific area in your home to work. It will help your brain better demarcate the type of activity you carry out, and it’s also beneficial for your posture.

7. Minimize distractions

In most cases, social media is the main culprit that diverts attention from the task at hand. It’s designed to be easily accessed, but that quick browse might turn into half an hour (if not longer) of wandering aimlessly online. When working from home, in a relaxing environment, with no one watching, you might forget about duties and let yourself sucked in. To reduce this risk, log out from all your social media accounts and remove their shortcuts from your browser. Another option would be for you to work primarily in a private browser window. With no autofill convenience whenever you perform a web search, it’s less likely that you’d take social breaks too often.

8. Take clear breaks

To avoid getting distracted from what needs to be done, you might think that not taking breaks at all is a good idea. But just as it goes for working in an office, taking five to relax is recommended for remote workers as well. However, rather than spending those breaks in front of your laptop/PC, use this time to get away from your desk, stretch or have a quick talk with a close one.

9. Set a definitive finish time

While some might struggle to keep going through their to-do list, others might get immersed into their work so much as to lose track of time. At the office, your colleagues’ preparations to leave at the end of business hours remind you that it’s time for you to do the same, whereas at home there’s no such “trigger”. To avoid getting so caught up in your activities that you forget to “clock out”, set an alarm to mark the end of your business day. This way, you start saving your work and allow yourself to enjoy the evening. After all, you have a work-life balance to keep.

10. Plan out on what you’ll be working ahead of time

With your workday over, take a couple of minutes to plan the activities for the upcoming one(s). Of course, it’s possible for things to change, however having a general overview of what is next on your to-do list saves you time and effort in figuring out what you need to be doing in that future moment. Committing to an agenda that outlines your assignments before you begin will make it more “official” when you actually get started on it.

Insights from our CEO

Here at Office Timeline, we take working from home seriously – and we’ve been doing it for years. We work in distributed teams across the US and Europe and could recognize our voices even in a bar full of people playing beer pong. I'd be more than happy to share some of the lessons we’ve learned over the years, hoping you can avoid our mistakes:

  • Control your chattiness. Because you spend a lot of time with no one to talk to, that really makes you want to have an in-depth conversation with basically anyone: the delivery guy, the cashier at the store, the pharmacist. Observe this urge, contain yourself and let these poor people get on with their jobs.
  • Cover your webcam. It’s easy to forget you have an electronic eye that watches everything you do and everything you wear (or don’t), so do yourself a favor and put a piece of dark tape over it. Better safe than sorry.
  • Don’t eat into your microphone. We all get a little hungry sometimes, especially during the afternoons when most conference calls tend to happen. But nobody wants to hear you constantly snacking while they’re trying to have a conversation. It’s too distracting for them and probably not very healthy for you.
  • Get a pet to keep you company. If being alone is driving you crazy, consider adopting a pet; just make sure you understand this is a long-term commitment. Our team members have a variety of companions – mostly cats and dogs, but also fish, parrots or even squirrels – who are more than welcomed to join our team meetings.

How we spend our days is how we spend our life, it is said. During uncertain times that are marked by a sense of instability and chaos, adding structure to our workdays may seem insignificant, but it can actually go a long way. Working from home turns us into managers of our own time and, with a bit of discipline and a clear timeline of what needs to be done, we can make the most of it.
