Some People Tests Positive After Being Vaccinated. How Can This Happen?

There’s a high possibility that you can already be infected and not know it (asymptomatic) when you get the vaccine.

There are reports swirling around about some people test positive for the coronavirus even though they have already received one or both doses of a COVID-19 vaccine.

How can this happen?—According to experts, cases like these are not surprising and do not indicate that there was something wrong with the vaccines or how the vaccines were administered. So, here let us break down the reasons why this happens…

Vaccines don’t work instantly. It will take a few weeks for the body to build up immunity after receiving a dose. The vaccines from Pfizer-BioNTech and Moderna, both require a second shot a few weeks after the first to reach full efficacy.

Vaccines don’t work retroactively. You can already be infected by COVID-19 and not know it when you get the vaccine or even if you recently tested negative. The infection can continue to develop after you get the shot but before its immunity fully takes effect, and then show up in a positive test result.

Vaccines prevent illness, but maybe not infection. COVID vaccines are being authorized based on how well they keep you from getting sick, needing hospitalization and dying. Experts don’t know yet how effective the vaccines are at preventing the coronavirus from infecting you from the start, or at keeping you from passing it on to others. That is why it’s important that people who already received the vaccine should keep wearing the facial masks and maintain social distancing.

Vaccines aren’t perfect. The efficacy rates for Pfizer-BioNTech and Moderna vaccines are extremely high, but they are not 100%. With the virus still spreading out of control in major countries like in the United States, some of the recently vaccinated people were still bound to get infected one way or another.
