How long does mRNA from Moderna or Pfizer vaccines last in the body? Good article explains.

[cdemundo]

Some unfounded fears of persistence of mRNA in the body after Pfizer or Moderna vaccination are out there.

We know that mRNA is fragile, that is why it has to be kept cold.

More in depth explanation in the article.

clarify "unfounded fears" was just "fears"

"Fear" is a poor choice of words and makes you look like an anti-vaxxer spreading FUD.

 

So far only one country (Israel) seems concerned enough about the long term effectiveness that they want to order a 3rd booster shot.  

 

The problem with that is a lot of people around the world are still waiting for their 1st shot.  So there are ethical considerations.

They are just not sure how long the vaccines last is all.  So far they seem to be going strong up to at least 6 months to a year.  So far only one country, Israel, seems to be concerned about effects after that which is why they say they are ordering booster shots.  

 

The problem with that is a lot of people still have not received their 1st shot.  So there are ethical considerations.

"How long the vaccines last" as you put it refers to the immunity or protection from COVID the vaccine provides.  Nothing to do with how long the mRNA or spike proteins last in the body.

This is an entirely different question, which you don't seem to understand.

 

Israel is not concerned about "after effects" they are concerned about waning immunity.

 

I am guessing you didn't look at the article because your reply has nothing to do with what the post is about, ... beyond that, you just don't seem to have a very clear understanding about anything related to the vaccine discussion.

 

If you think I am an anti-vaxxer from this post and if you think that the University of Nebraska Med school is a source of disinformation ... well, have a lovely day.

Nice to hear you are concerned about ethical considerations.

The problem with rich countries ordering boosters is that is a lot of people in less than 1st world countries still have not received their 1st shot.  So there are ethical considerations.

 

Not just ethical considerations but major virological considerations too.

 

It is important that as many people globally become vaccinated. It is perhaps more important that those in poorer countries of higher population density become vaccinated as soon as possible ahead of those in wealthier nations. 

 

The significant risk includes Covid-19 outbreaks in areas and countries of high population density which could result in further variants, it may be that the evolution of the virus drifts toward variants which do not concern us, but there is also a risk that the evolution of the virus in areas of unvaccinated high population density drift into variants of significant concern which can evade the vaccines.

 

The risk here is that those variants come back to our own countries and cause significant problems. 

It not through any benevolence that poorer countries of high population density are vaccinated, it is through self preservation that they need to be.

As Thailand faces its worst COVID-19 outbreak, authorities have been forced to change the country's vaccine regime and, in a world first, AstraZeneca will be used to boost immunity among people who have already been given the Sinovac shot.
