Switzerland was the first country in Europe to approve the corona vaccine from the US pharmaceutical company Pfizer and its German partner Biontech in a regular process.
What happens when you have been vaccinated. Here are some questions answered.
What about vaccination?
The vaccine is given by two injections into a person’s arm three weeks apart. According to large-scale testing by vaccine developers Pfizer and Biontech, the vaccine, called BNT162, provides 95 percent protection against the coronavirus.
Will I have a headache or fever after vaccination?
The side effects were mild to moderate and disappeared quickly, according to the publication of the Pfizer / Biontech study results. The most serious side effects occurred after the injection of the second dose: in 3.8 percent of cases fatigue and in 2 percent of cases headache. Older adults 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 (mRNA) technology. This approach uses the human body’s messaging system to turn cells into disease control factories.
Messenger RNA instructs cells to make proteins that are necessary for almost all human functions. With the new vaccines, mRNA produced in the laboratory is smuggled into human cells to produce virus proteins that ultimately trigger an immune reaction.
What protection does the vaccine offer?
Just one week after the second injection, about four weeks after the first, the vaccine offers complete protection against the disease. However, it is not clear whether the vaccine will also prevent the vaccinated person from continuing to transmit the virus. Some vaccines do, like hepatitis A, but others don’t. Vaccination against Covid-19 prevents the outbreak of the disease, but does not necessarily prevent the vaccinated person from being contagious. With this, a vaccinated person can still transmit the virus to other people who can later become ill.
Is corona vaccination protection sustainable?
It is also not clear yet how long the vaccine will protect against the disease. Experts believe this will only be clear in a few months. “Until then, it’s best to avoid the restaurant and other face-to-face meetings with large numbers of people,” recommends Anita Shet, 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 for vaccinated people either: keep your distance, wash your hands regularly, and wear a mask.
Michelle Barron, senior medical director of infection prevention at UCHealth in Colorado, cautions: “Like any other vaccine, this one may work very well in certain subgroups of patients and not so well in others. Are you free to get on a plane or invite 30 people to your house? Probably not. “(SDA)
