What about immunity?
A study by the prestigious King’s College in London shows that antibody-based immunity to the coronavirus usually disappears after a few months.
Researchers from the Shanghai Public Health Clinical Center, among others, studied 175 recovered, mild Chinese covid-19 patients. This involved measuring the amount of neutralizing antibodies in the blood plasma several weeks after they had recovered from the infection. In a third of the participants, the level of these antibodies was quite low. In ten patients, the amount of antibody was not even detectable. Briefly, in the first weeks, the researchers found high antibody levels in 60% of the cases. After three months, these could only be found in 17% of the cases.
The King’s College study confirms earlier suspicions about the disappearance of antibodies to the coronavirus. The researchers regularly checked the blood for antibodies of about 70 people who tested positive for the virus. They did this until 94 days after the onset of symptoms.
Travel during Corona pandemic
The government’s advice is not to travel unless necessary. Every trip increases the chance of more infections in the Netherlands and abroad.
Does a wedding require testing for corona?
The government rules are clear; a wedding ceremony may have up to 30 people present. This includes children and excludes staff.
Are corona tests reliable?
In 2021, the government wants to move to more widespread and more frequent coronavirus testing, including people without symptoms. This will create more opportunities to open up society and at the same time keep a good eye on (the spread of) the virus.
There are many coronaviruses but this disease is officially called SARS-CoV-2 or COVID-19. For convenience, we will call it coronavirus in this blog.
