For the past few months we have been inundated with information regarding the COVID-19 vaccine and many of us have been fortunate enough to get it.
Now that many of you have received the vaccine, or at least the first dose, the most frequent question I have been asked is "how do I know if it worked"?
Per the CDC website none of the COVID-19 vaccines can cause you to test positive on viral tests, which are used to determine whether or not you have an active COVID-19 infection. The goal of this vaccination is for your body to develop an immune response to COVID-19. It seems reasonable that you may test positive on some antibody tests, antibody tests are used to indicate if you had a previous infection and have some level of protection against the virus. According to the CDC the jury is still out on how COVID-19 vaccination may affect antibody testing results. I reached out to Pfizer via email to see if they had more information and they replied that "antibody testing is not currently recommended to assess for immunity to COVID-19 following mRNA COVID-19 vaccination."
In summary, at this time there is no reasonable way to assess if one is immune after receiving the vaccine, however Pfizer's clinical trial showed that 95% of participants were immune after receiving 2 vaccinations.
As I am about to send out this month's column Johnson & Johnson announced that their Vaccine Candidate is 72% effective in the US. They will be applying for emergency FDA approval this week. As more information becomes available I will share it with you.
Until the next time,
