63% of the elderly have antibodies six months after Covid-19 vaccination

Study carried out by the IGC reveals that 63% of the 260 elderly over 70 who have been followed up have  detectable antibodies 6 months after Covid-19 vaccination. The data obtained after 6 months, referring to the Pfizer/BioNTech vaccine, confirm that, similarly to what happens with other vaccines, the decrease in antibodies generated by vaccination is faster in the older population.
