Dear MEL Topic Readers,
You can still get infected with Covid-19 after being vaccinated.
Various types of coronavirus vaccines are being manufactured, distributed, and injected to people in the US, UK, and other countries. But don’t expect that the vaccine will make you and others immune completely from coronavirus.
Basically, vaccines carry a small stretch of genetic material, which instructs cells in the body to make a small piece of material that looks like a part of the virus. Those bits then, get recognized as a foreign invader by the immune system, and it starts to make antibodies and immune cells. If the vaccinated person gets infected, those antibodies and immune cells recognize and neutralize the virus. But this development process normally takes a few weeks. If a vaccinated person is exposed to coronavirus before the body develops the defense system, he or she could get sick. Also, like the flu shot, no vaccine is 100% effective. Furthermore, the protection period can fade over time and might need a booster shot years later. And variants are already emerging and they could stay and increase over time, just like the flu. Lastly, even if you are vaccinated and have developed an immune system in your body, you could be exposed to the virus and transmit it to others. For example, if a vaccinated person had lunch with someone who is infected, the person is exposed to the virus. If the same person got on the crowded train without a facemask, he or she could transmit the virus to those who are unprotected or haven’t been vaccinated.
So, just like the flu shot, the coronavirus vaccine is not a silver bullet. Face masks and social distancing seem to be the new norm at least for a while.
