Switzerland was the first country in Europe to approve the corona vaccine from the US pharmaceutical company Pfizer and its German partner Biontech in an ordinary process.
What happens when you have been vaccinated. Some questions about this are answered below.
What happens with the vaccination?
The vaccination is given by two injections into a person’s arm three weeks apart. According to large-scale tests by vaccine developers Pfizer and Biontech, the vaccine, called BNT162, provides 95 percent protection against the coronavirus.
Will I have a headache or a fever after the vaccination?
The side effects were mild to moderate and quickly subsided, according to the publication of the study results from Pfizer / Biontech. The most serious side effects occurred after the injection of the second dose: In 3.8 percent of the cases fatigue and in two percent of the cases headache. Older adults would have tended to have fewer and milder side effects.
The vaccine developed by the partners is the first of its kind to use so-called messenger RNA technology (mRNA). This approach uses the human body’s messaging system to turn cells into disease control factories.
The messenger RNA instructs cells to make proteins that are needed for almost all human functions. With the new vaccines, mRNA produced in the laboratory is smuggled into human cells in order to produce virus proteins that ultimately trigger an immune reaction.
What protection does the vaccine offer?
Only one week after the second injection – around four weeks after the first – does the vaccine offer full protection against the disease. However, it is unclear whether the vaccine will also prevent the vaccinated person from transmitting the virus further. Some vaccines do, such as the one for hepatitis A, but others don’t. Vaccination against Covid-19 prevents the outbreak of the disease, but not necessarily that the person vaccinated is contagious. This means that a vaccinated person may still be able to pass the virus on to other people who can then get sick.
Is the corona vaccination protection sustainable?
It is also not yet clear how long the vaccination will protect against the disease. Experts believe that this will only be clear in months. “Until then, it’s better to avoid the restaurant and other face-to-face meetings with large numbers of people,” recommends Anita Shet, an infectious disease specialist at the Johns Hopkins Bloomberg School of Public Health.
Does the vaccine mean a return to normal life?
Probably not at first. Scientists advocate not issuing the rules of action to vaccinated people either – keep your distance, regularly wash your hands and wear a mask.
Michelle Barron, senior medical director of infection prevention at UCHealth in Colorado, warns, “Like any other vaccine, this one can work really well in certain patient subgroups and not so well in others. Are you free to get on a plane or invite 30 people to your home? Probably not.” (SDA)
