Good morning and welcome to COVID Transmissions. It has been 465 days since the first documented human case of COVID-19. We are 100 days into the second year of the COVID-19 pandemic. Please note this will be the last issue of COVID Transmissions for this week. The Jewish holiday of Purim is on Friday, and I am taking the day off from work, including the work I do on this newsletter. I will be back on Monday, which I am told will be part of the month of March, a month that I’m not sure we ever really left, back in 2020. Hopefully this March will be a month of renewal and new growth, as it should be, as we gain increasing control over the pandemic.
Regarding the NIH article you cited "Is One Vaccine Dose Enough After COVID-19 Infection?", the referenced study referred to people who tested positive for antibodies prior to getting the vaccine. This is just a subset of those people that were infected with COVID-19, and the article should have been more clear on this point.
The article raises the question of whether there is any substantive benefit to getting the second shot for those that tested positive for antibodies prior to getting the first shot. Two related questions then arise:
1. Is there any harm to giving the second shot to people that tested positive for antibodies prior to getting the first shot?
2. Is there any similar benefit/harm to people that recovered from COVID-19 but no longer test positive for antibodies?
