Dear ROACH: I have been doing regular COVID-19 tests which have always been negative. Recently, only a few days ago. I had an antibody test six weeks ago, which was also negative. But my antibody test this time was extremely positive. I am very careful to protect myself and I have no symptoms at all! I am scheduled to receive my first vaccine tomorrow. What should I do? – CW
answer: With frequent negative wiping tests and asymptomatic, your chances of having COVID-19 are lower than the average person in your community. But if your community is affected as badly as you may have seen in most cases, then there’s a good chance you’ve had a recently asymptomatic infection.
The antibody test results you submitted show very positive results using highly specialized laboratory tests. Although it is possible that this is a false test result. But I suspect you have COVID-19 patients who are so mild that you notice they don’t have any symptoms.
You may have another case of resistance to COVID-19, but that immune system can quickly deteriorate. It is recommended that you receive the vaccine on schedule. The vaccine can be safely taken as long as you do not have symptoms. However, those treated with a monoclonal antibody in the case of COVID-19 should wait 90 days before receiving the vaccine.
Dear ROACH: I know of someone who received the first and second Moderna vaccine and did not experience any side effects from one of them. Does that mean the vaccine isn’t working, or does that mean their system is pretty healthy? Everyone’s talking about side effects But nobody talks about it if you don’t have side effects. Please clarify, as I am going to get my second vaccine this coming Saturday.
answer: I often hear doctors and patients describe vaccine reactions, such as arm pain and fever, as evidence that “the vaccine is working.” It is common to worry that no reaction means the vaccine is not working. However, that’s not the case. Even people without any side effects (most people have at least slight arm pain) benefit from the vaccine.The Moderna vaccine is 94% effective at preventing infection.
It’s true that people with a history of COVID-19 infection are more likely to experience side effects such as fever or fatigue. So I won’t say that people you know who have no side effects always need a “healthy” immune system. The immune system needs to be fully controlled to protect you from invaders. But also to avoid autoimmune reactions But that means they are less likely to have COVID-19 in the past.
Part of the danger with COVID-19 infection is the body’s immune response and the inflammatory response to the virus. I would guess that people who have had a severe reaction to the vaccine might be someone who is more likely to be at risk of serious COVID-19 complications. not
