Covid Vaccination News - mRNA Vaccines 5 Times More Effective Than 'Natural' Antibodies From Infection.

COVID vaccines 5 times more effective at protecting against COVID-related hospitalization than prior infection alone

A large-scale study by the VISION network of the US CDC has shown that protection against the SARS-CoV-2 virus provided by the mRNA vaccines is 5 times more effective at preventing hospitalizations that any protection produced by infection with the virus. Whilst neither is 100% effective at preventing infection, by far the best protection against becoming seriously ill is provided by the vaccinations developed by medical science.

In the over 65 age-group, this differential rises to 20 times more effective that previous infection!

This data provides powerful evidence that vaccinations offer superior protection against COVID-19 than relying on natural immunity alone. Many have been asking if they should get vaccinated if they’ve already been infected – this research shows the answer is yes.

According to the press release by the Regenstrife Institute, who analysed the data provided by the VISION Network:
Researchers from the CDC’s VISION Network gathered data from more than 201,000 hospitalizations in nine different states. About 7,000 people in that group fit the criteria for this study. The research team analyzed the number of unvaccinated individuals who had a positive COVID-19 test more than three months before being hospitalized for the virus as well as the number of individuals who received the Pfizer or Moderna vaccine and were not diagnosed with COVID prior to being admitted to the hospital. The research team found that overall, unvaccinated adults with a previous COVID-19 infection were about five times more likely to be hospitalized than those who were vaccinated.

The data analysis also found among adults older than 65, overall mRNA vaccines were nearly 20 times more effective at protecting against hospitalizations than prior infection alone.

The study findings are consistent with laboratory evidence that mRNA vaccines create high levels of antibodies, whereas those who recover from COVID-19 have varying levels of antibodies, especially if they experienced mild symptoms or were asymptomatic.
The findings are published in the CDC's Morbidity and Mortaility Weekly Report (MMWR):
Summary

What is already known about this topic?

Previous infection with SARS-CoV-2 or COVID-19 vaccination can provide immunity and protection against subsequent SARS-CoV-2 infection and illness.

What is added by this report?

Among COVID-19–like illness hospitalizations among adults aged ≥18 years whose previous infection or vaccination occurred 90–179 days earlier, the adjusted odds of laboratory-confirmed COVID-19 among unvaccinated adults with previous SARS-CoV-2 infection were 5.49-fold higher than the odds among fully vaccinated recipients of an mRNA COVID-19 vaccine who had no previous documented infection (95% confidence interval = 2.75–10.99).

What are the implications for public health practice?

All eligible persons should be vaccinated against COVID-19 as soon as possible, including unvaccinated persons previously infected with SARS-CoV-2.

So, it's a no-brainer. Get vaccinated and get the booster when available, unless, of course, you want to end up on a ventilator. It won't guarantee you don't get infected or even need hospital treatment, but it will significantly reduce your chances of doing so.

The sad thing is that a simple no-brainer is beyond the wit of those covidiots who have fallen for the antivaxxer hoax being promulgated by fruitloop extremists, often with a pro-Trump, political agenda.
