The vaccine against the coronavirus is long awaited and many hope that life can soon return to normal.
Vaccine coordinator Richard Bergström has previously stated that we can probably start going on holiday again by the summer.
But there are still questions about how long the protection will last - and how often you will need to take the vaccine so that the risk of infection does not increase again.
Gunilla Karlsson Hedestam, professor of immunology, emphasizes that it is important to follow developments to get as good a picture as possible of how the vaccine works.
- We follow it in real time.
It has now been three months since the first countries received the vaccine.
We see no worrying fading of protection.
Those who have had a natural infection appear to have protection for nine months.
It gives us a certain feeling about the vaccination, she says in Aktuellt on Monday night.
Restrictions may need to remain
It is not certain that those who are vaccinated now will also be protected in the autumn - and it is unclear how many will choose to be vaccinated.
- We will not vaccinate everyone during the first half of the year.
We will not achieve the high coverage required for us to be able to relax.
- I think we must keep some restrictions.
For example, those that prevent large crowds where many are displayed in a dense environment.
Karlsson Hedestam also points out that it may be relevant to get vaccinated again this autumn, even if it is taken this spring.
- Yes, it can be, it can possibly be recommended to certain groups.
The vaccine companies are planning for that now and we hope that they have that foresight politically.
