A corona vaccination from BioNTech / Pfizer and Moderna is not enough to fully protect you. That is the reason.
Both BioNTech / Pfizer and Moderna’s corona vaccines are now approved. According to experts, each remedy requires two doses. The second dose should therefore be a few weeks after the first Corona vaccination administered. There is an important reason for this.
Corona vaccination: That’s why two doses are necessary
To ensure reliable and long-lasting protection, the corona vaccine from BioNTech / Pfizer and Moderna should be injected twice with an interval of a few weeks. Because the study by both companies was aimed right from the start to examine the effectiveness of the corona vaccination with more than one dose.
In the specialist publication for the phase III study of BNT162b2, the corona vaccine from BioNTech / Pfizer, “the observed efficacy between the first and second dose was 52 percent”, (via Pharmacy magazine). So this means that after only one corona vaccination you do not have full protection against Sars-CoV-2. And indeed there was according to WBRC already has cases where people who have only received a dose have contracted the coronavirus.
After the first dose of a vaccination, the immune system is stimulated to produce antibodies, for example, but the reaction is not yet strong. “Only after the second does a so-called boost effect occur, the immune system really jumps on and is prepared for a later infection with Sars-CoV-2,” says the pharmacies around the world.
A vaccination takes time to work
Even after the second corona vaccination, it would take time before you are protected. “It will take some time for your body to build a robust immune response to protect you, and unfortunately that protection won’t come once the needle pierces your skin,” said Wesley Willeford, medical director of disease control at Jefferson County Health Department in Alabama , across from WBRC im Video-Interview.
BioNTech / Pfizer last warned to increase the interval between the two doses of the corona vaccine due to scarcity after the WHO suggested it. You can find out here what differentiates the corona vaccines from BioNTech / Pfizer and Moderna.
