Is having had COVID 19 + one shot of vaccine equal to adequately protected from COVID again?

Asked by flo (13202points) 1 month ago

Someone was saying you don’t need the second shot of vaccine if you were a victim of COVID 19. Is that factual?

The experts are saying no and recommending you get both vaccinations even if you have had covid-19. I had covid-19 in December and I did get both Moderna shots.

Get both if it was a two shot vaccination plaan. . . also get ready for a booster in the Fall of 2021.

No. Totally not true. You need both shots, unless you get the Johnson and Johnson shot.

No. Remember we are dealing with varients. Get every protection.

Makes logical sense to me that the first shot after already having had covid would act like a booster. A biologist I know says the same. Sometimes what seems logical does not actually pan out as being correct though, we won’t know until they test it. Since there is no specific study done to know for sure, the recommendation is to still get both shots. The FDA and CDC would only be concerned with whether people are having severe side effects from the second shot, they wouldn’t care right now if the first shot is sufficient. Most likely, eventually, it will be evaluated either in the US or another country.

Also, it might matter how long ago the person had covid. Safer to get both shots. Too much unknown.

No. You need both shots of the vaccine to be fully covered, or as covered as it is possible at this time.

Do you all just parrot what you hear regarding current recommendations without actually thinking about why it might be logical that one shot would act as a booster for people who had COVID. Stop and think about it.

I googled and here is an article. Looks like Cedars-Sinai investigating it.

I’m not telling anyone to only get one shot, I’m just saying it’s not a crazy idea that it might be enough.

After seeing this Q last night, I messaged with a friend who is a researcher at NIH about this.
This is his response on this topic:

“The difference between the immunity level achieved by having had and survived the original strain of Covid-19 and that of the immunity level achieved by getting the vaccines is notable.
For example, if you had a fairly light case of Covid six months to a year ago, your natural protection is much less than is created by the recommended dose of the manufactured vaccine, and your defense against mutations like (and including) the Delta variant is much much lower.”

I would take the advice of doctors and get both shots. Why risk your life going under the assumption that having had Covid makes you immune?

Caravanfan's avatar

@chyna It doesn’t. I’ve seen cases of Covid after people have had covid.

^ I’ve had a cousin and a niece that had it twice, prior to the vaccine.

Just to be clear, I’m not saying COVID necessarily makes you immune, there have been people who get COVID twice as we all know, but many studies are showing lasting immunity. Much like the vaccines work 90% of the time, but then there are breakthrough cases.

This Q is about whether the body creates some memory and then a single shot builds on that in the immune system.

Scientists are studying it, and not only in the small study I posted.

Comparing the standard two shots to having had COVID is not this Q. This Q is two shots compared to covid plus one shot.

There is also a mix study happening in the UK. One dose AstraZeneca one dose Pfizer. Of course no one should be mixing and matching right now except in very unique cases (I know of one person who did mRNA first dose and J&J second dose) but so far the mix study is showing a strong immune response.

Moderna was being tested in half dose after the initial approval, I don’t know if that study was completed. J&J has a two dose study going on. Both make sense as a hypothesis worth testing, but that doesn’t mean we start playing with how it is being administered now.

Accepting that scientists are interested in the results of single vaccine after COVID doesn’t mean people should only get one vaccine, it just means science continues to look at how the immune system and vaccines work regarding COVID and possibly the science will evolve to different recommendations.

Doctors right now are only going to prescribe (recommend) it be given how the FDA approved it, which is two shots period, which they should and makes sense scientifically currently.

If one dose is sufficient for people who had COVID it could really help in countries like Brazil and India.
