Show me a study where the efficacy of Covid vaccines is higher than the flu shot. The flu shot is always 50-60% efficacy. Covid started higher but continually drops. That is because the spike protein is a very narrow, focused attack that went after the original virus. Two, three variants later, and the original mRNA is declining. Boosters may help, but positive tests keep on coming with vaxxed folks, so the optics are not good.
The flu vaccine is not a good example there is a large family of flu viruses (like there is a large family of coronaviruses where sars-cov-2 is only one of them )
which makes the flu vaccine much harder to make, if you predict it will be A- H1N1 and B-Victoria and put something to fight those and it ends up being A-H3N2 instead it is more or less useless.
Now as for Covid-19
[Link: cdc.gov]
"In a multistate network of U.S. hospitals during January–March 2021, receipt of Pfizer-BioNTech or Moderna COVID-19 vaccines was 94% effective against COVID-19 hospitalization among fully vaccinated adults "In the meantime, Anthony, people who have had Covid have a broader immunity, not less, and broader protection.
NIH - “a durable, lasting immunity”
[Link: nih.gov]BBC - natural immunity matters, and add an injection might give you “super-immunity”
[Link: bbc.com]did you actually read the articles you posted?
Like I said, both become lessons to your body to better defend itself. So on that we agree but the first link is almost a year old and makes no comparisons between the two and just states the obvious which we agree with. having cought covid once does help train your body for the second time
The second one
Neither gives you complete protection versus infection, but the immunity you get from either seems to protect you pretty well from serious illness," said Prof Finn, from the University of Bristol.
Antibody levels are, on average, higher about a month after vaccination than infection. However, there is a huge gulf in antibodies between those who are asymptomatic (who don't make very much) and those who get a severe bout of Covid."so if you have severe case of Covid the bodies defenses are close to that of the vaccine, but there is still an advantage for the vaccine, but if you are asymptomatic there is almost no benefit.
also later on
"Where does this leave the balance between more vaccine and virus?
There is clear evidence that adults who have not had any vaccine dose will have stronger immune defences if they do get vaccinated, even if they have caught Covid before."Merry Christmas and a healthy and successful New Year!
same to you
