The answer, which also considers which types of professionals are needed at each stage of development, is complicated. The effectiveness and life-saving nature of vaccines leads people to pose the same question whenever a public health crisis, such as COVID-19, Zika or Ebola, hits the news cycle: “When will a vaccine be available?” According to the World Health Organization (WHO), severe side effects from vaccines are rare, and individuals are “far more likely to be seriously injured by a vaccine-preventable disease than by a vaccine.” It began many years ago, but the urgency of having something for COVID certainly accelerated the work.”Ĭontrary to what anti-vaccination communities assert, vaccines are both safe and effective, and mRNA vaccines do not alter a recipient’s DNA. “The Moderna and Pfizer vaccines are a completely different method of making vaccines from anything that’s been done before,” Waldman said. This allows the body to recognize the infection and fight it off if it encounters the same material in the future, without injecting any actual coronavirus into vaccine recipients.

These COVID vaccines use messenger RNA (mRNA) - or genetic material that gives instructions - to teach cells to make a spike protein found on the surface of the coronavirus. Some newer vaccines, such as the COVID vaccines developed by Moderna and Pfizer-BioNTech, rely on genetic material to teach the body to recognize and ward off infections, instead of using a weakened virus. “The idea is to take either a related - and less lethal - pathogen, or a weakened version of the disease-causing pathogen itself, and expose the body to that so that it prompts the ability of the body to remember the next time it sees the actual virus or bacteria that you want to protect against, and the body can respond to it right away with a response,” Waldman said. It may seem counterintuitive, but the key ingredient in an effective vaccine (PDF, 219 KB) is often an inactive or weakened version of the very bacterial or viral infection it was created to prevent. Vaccines weaponize our immune systems by imitating the infection, which in turn prompts our bodies to create the same antibodies it would need to fight a full-blown version of that illness. When we get sick, we produce antibodies, or proteins, that help our bodies fight illness. Though it’s common to hear the terms “immunization” and “vaccine” used interchangeably, they actually describe different things. It’s the way to stop the pandemic.”Īlthough there is mistrust and misinformation surrounding vaccines, there are rigorous processes that vaccines must go through before they can be proven safe and effective and, ultimately, distributed to the public. “It’s really a miracle,” Ron Waldman, MD, MPH, a global health professor in the George Washington University’s Milken Institute School of Public Health, said of the development of COVID vaccines. Vaccines help mount a collective public health response to protect the health of communities and countries.

For instance, unvaccinated children who are exposed to measles may not be able to resist the disease because their bodies have not had a chance to build antibodies to fight it. Recent outbreaks of COVID-19, measles, Ebola and Zika have demonstrated that people are more vulnerable to diseases if they have not been vaccinated against them.
