ONGOING VACCINE RESEARCH AND DEVELOPMENT AT PFIZER

The concept of "severe COVID-19" can be a frightening one, especially when the term itself is so often misunderstood or confused with having self-assessed severe symptoms of COVID-19.Approximately 80% of those who test positive for COVID-19 have mild to moderate illness.1 But adults 50 and older and

Terms like “quarantine” and “social distancing” have been a natural part of our lexicon since 2020. But many of us are not standing six feet apart in public spaces anymore or quarantining after a COVID-19 exposure prior to testing.

Wait, Marvel? On Pfizer.com? For some, comic books may seem to be simply a form of entertainment featuring fantastical characters and mythical plots. However, through the years, they have proven to reflect and even influence our society.

While preventative measures, including applying insect repellent and checking for ticks1, are recommended to help with personal protection, there’s limited evidence that they’re having an impact on reducing the annual number of cases of Lyme disease, according to Raphael Simon, PhD, Senior Director

Throughout the COVID-19 pandemic, messenger RNA, or mRNA, has been in the spotlight for the critical role it’s playing in the first-ever approved mRNA vaccine.1 But in fact, Pfizer and BioNTech had entered into a worldwide collaboration agreement in 2018 to work on an mRNA vaccine for a different vi

Bacterial meningitis strikes fast.

In 2020, as Pfizer and BioNTech were still developing the COVID-19 vaccine, Julie Jenson was thinking about how to distribute that vaccine to every country around the world, regardless of that country’s means.

Edward Jenner changed the world when he used cowpox virus to inoculate a young boy against smallpox.1 Less than 200 years later, smallpox was eradicated from the Earth.2 Dozens of vaccines have since been created, leading to dramatic improvements in public health as well as a marked decline in death

Ever since the first vaccine was developed in 1796 to treat smallpox,1 several different methods have been created to develop successful vaccines.

ON TUESDAY, DECEMBER 31, 2019, Chinese authorities alerted the World Health Organization to a mysterious virus causing pneumonia-like illness in a small cluster of patients in the city of Wuhan. Shortly after, the novel virus was identified as SARS-CoV-2.

As the potential threat of COVID-19 became clear by early 2020, teams across Pfizer sprang into action. Together, they worked to better understand the novel virus. Hospitals were filling, and no one was sure how best to treat the people who were sick.

As the weather cools, viruses have a tendency to spread with more ease. That’s because people tend to spend more time indoors, where germs can circulate from one person to another through the air or close contact.

At the height of the COVID-19 pandemic, the onset of a fever, cough, sore throat, or sniffle may have led to frantic online searches for “Is this COVID-19 or the flu?”Even as the Public Health Emergency for COVID-19 has ended,1 it’s still a good idea to understand the similarities and differences be

Vaccines can train your body to prevent sicknesses before they even start.

Vaccines are one of the greatest health interventions ever developed. They’ve been cited as being as important to keeping communities healthy as having access to clean water and safe sanitation.1 Through scientific investment and ingenuity, today we have multiple vaccine technology platforms that h

The instinct to protect a baby starts when it's in the womb. Some of the most common ways a mother does this is through receiving regular prenatal care, taking prenatal vitamins, and prioritizing a healthy diet and rest.

In our increasingly interconnected world, where illness can spread quickly from person to person, and even country to country, vaccines can offer protection.

In the first few months of their lives, infants experience new sights, sounds, scents, and textures. During this time, they also make contact with new organisms.

Mosquitoes won’t just ruin a cookout or leave angry red welts on your skin after a blood meal; the little buzzers might  also transmit serious diseases. Mosquitoes are "silent" feeders; their siphon-like mouthparts can quickly pierce human skin and feed on blood without causing any notice, says Pat

Viruses are different from one another in many ways, including how well they spread and which parts of the body they attack. One thing most viruses have in common, though, is that they have resourceful ways to survive our efforts to kill them.

Childhood vaccination rates dropped drastically during the COVID-19 pandemic, and it could potentially mean a resurgence of diseases we've long had under control. Approximately 66% of children aged 5 months in the United States were up to date for all CDC-recommended childhood vaccines in 2016-2019
