39.3C is a bloody high fever for a vaccine reaction!
Indeed. If you know the cause and the effect is temporary then there's no need to worry.

South Africa will buy doses of Oxford-AstraZeneca’s COVID-19 vaccine at a price 2.5 times higher than most European countries, the health ministry said on Thursday.
The continent’s worst virus-hit country has ordered at least 1.5 million shots of the vaccine from the Serum Institute of India, expected in January and February.
COVID vaccines might lose potency against new viral variants
Newly emerging, fast-spreading variants of the coronavirus might reduce the protective effects of two leading vaccines.Nature bioRxiv
Michel Nussenzweig at the Rockefeller University in New York City and his colleagues analysed blood from 20 volunteers who received two doses of either the vaccine developed by Moderna or that developed by Pfizer–BioNTech (Z. Wang et al. Preprint at bioRxiv https://doi.org/frdn; 2021). Both vaccines carry RNA instructions that prompt human cells to make the spike protein that the virus uses to infect cells. This causes the body to generate immune molecules called antibodies that recognize the spike protein.
Three to 14 weeks after the second jab, the study participants developed several types of antibody, including some that can block SARS-CoV-2 from infecting cells. Some of these neutralizing antibodies were as effective against viruses carrying certain mutations in the spike protein as they were against widespread forms of the virus. But some were only one-third as effective at blocking the mutated variants.
Some of the mutations that the team tested have been seen in coronavirus variants that were first identified in the United Kingdom, Brazil and South Africa; at least one of these variants is more easily transmitted than other forms of the virus now in wide circulation.
The findings suggest that vaccine-resistant variants might emerge, meaning that COVID-19 vaccines could need an update. They have not yet been peer reviewed.
For the motherland!I'll become sober then. Not an option.
Serbia is in Europe but not in the EU, so it's vulnerable to Chinese loansharking.I just wondered why the Chinese and Russian vaccines are not approved in Europe (but in various other countries like Serbia).
I pinged a friend at the Dutch GMO authority, who need to do environmental impact assessments for the vector vaccines, and she says that the Russian one is nowhere to be seen.
So... did they not bother brining it on the market here, did nobody buy it here, or what's the reason ?

Particles of SARS-CoV-2 (green) lurk in a study participant’s intestinal cells 92 days after the onset of symptoms. Nothing to do with the news, but fluorescent microscopy makes beautiful images.
C'mon, you know that this year is ‘2020 won’ and the next is ‘2020 too’.
There's nothing to worry about! As long as some scientists keep their funding.I don't need more bad news...

The death rate for Nipah virus is up to 75% and it has no vaccine. While the world focuses on Covid-19, scientists are working hard to ensure it doesn't cause the next pandemic.

Well, that's where the possibility of mutations are a worry? Don't blink when a crucial one happens.Interesting news. I don't see the article saying the Nipah virus is highly infectious, only highly lethal. It reminds me of Ebola.
It's spreading slowly but surely. It would be more of a worry if, as @Verbose said, it mutated.Interesting news. I don't see the article saying the Nipah virus is highly infectious, only highly lethal. It reminds me of Ebola.
