In a lengthy interview with US President Donald Trump in Fox news last night, the subject of the US Corona vaccine was touched on.

"We are very confident that we will have a vaccine at the end of the year," said Donald Trump, adding that it is unusually fast to get things approved by the US Medicines Agency in connection with the process.

Very optimistic by Trump

Around the world, many scientists are now working to try to get a good and functioning vaccine against the coronavirus. But succeeding at the end of the year goes against what many experts believe, which Trump is aware of.

- The doctors would say I shouldn't say that, but I will say what I believe.

Charlotta Bergquist, head of the Swedish Medicines Agency's infection group, is skeptical of Trump's statement.

- It is optimistic to think that there will be a year 2021. So I would think it is very optimistic to think that there will be one already this year. You have to have proper data for a vaccine that you give healthy people, she says in SVT's Morning Study.

What does data mean?

- Firstly, that you see a proper protective effect, which is meaningful and large enough, and that you have control over the most common side effects.

Must take his time

Kristian Borg, professor and chief physician at Danderyds Hospital, emphasizes the potential dangers of developing a vaccine too quickly.

- It is very important that you be careful about the evaluation of such things. As a neurologist, I can't help but think of the narcolepsy caused by the swine flu vaccine. You need to let it take your time to get an effective vaccine that has no side effects, ‚ÄĚsays Kristian Borg.

Over 67,600 people have so far died in the coronavirus viruses in the United States. In the last 24 hours, 1,450 new deaths were recorded, which is by far the most in the world. In the United States, there are over 1,150,000 confirmed infected.
