Vaccine’s ability to stop the spread of infection could affect planning – Vetenskapsradion Nyheter

The larger studies that have been done on the first vaccines to come out have only clearly shown that they protect against the development of disease.

It makes a difference of course life. But whether they prevent a vaccinated person from becoming infected and then spreading the infection without getting sick themselves is much more uncertain.

What we learn about how the vaccine works in real life could therefore affect vaccination planning later on, according to state epidemiologist Anders Tegnell of the Swedish Public Health Agency.

For example, it’s about about how important it will be to vaccinate the young people who do not belong to any risk group to slow down the pandemic. That is, those who do not usually develop serious disease, but who can still contribute to the spread of the infection.

– Normally, for most vaccines, if you reduce the disease burden, you also reduce the spread of infection, says Anders Tegnell.

– It is not yet known how much you will do with this completely new type of vaccine. But we have a few months, so we’ll probably get a lot more data. We will also get other vaccines that may be better at that than the vaccines we have now. Then we gradually have to take a position on which groups in society it is important to vaccinate.

It is said to be People aged 18 and over should receive vaccines once wider vaccination of the population has begun.
