Although more research is lacking, scientists say a longer period of protection against the coronavirus is undisputed, just as this vaccine did not cause serious side effects during the test phases.

Good news was received after a study looking for a solution to Covid-19. The Moderna vaccine produced antibodies for up to three months after 34 volunteers tested for the vaccine, according to a study published by the New England Journal Medicine. The event was reported this Thursday so many countries are trying to work with this laboratory.
Two types of antibodies to Covid-19 were examined 90 days after the second dose of the vaccine by researchers from the National Institutes of Health, which in turn was given 28 days after the first.
The protection time is obviously longer, but this is the first data in many months that has been independently validated according to a scientific journal.
Antibodies are part of the body's immune response to infection, along with B lymphocytes – immune memory, antibody production, and T – which kill infected cells.
A "slight" and expected decrease in antibody levels in the vaccinated volunteers was observed, but at an extent that remained high and above the natural immunity seen in patients with coronavirus who were recovering.
The US lab expects 20 million doses by the end of the year as it has the potential to produce extended immunity and is hoping 20 million doses will be distributed in the US.
The director of the Institute for Infectious Diseases, Anthony Fauci, recently mentioned to the AFP news agency that he was "certain" that the immune memory created by the vaccine would last for a while. "We don't know if it's going to be a year, two or five years, we don't know," he said. Only time will enable us to know.
Benjamin Neuman, a professor at Texas A&M University, described the study's news to AFP on Thursday as "generally quite positive," suggesting that even in the elderly, the immune response remained "fairly strong".
