Scientists at the Massachusetts Institute of Technology (MIT), in the United States, have developed a home test capable of measuring the levels of neutralizing antibodies against the infection caused by the coronavirus.
Studies have already shown that antibodies produced after an infection or by vaccines fall naturally over time. MIT scientists hope the new test will be used by people to track how long they will be protected against Sars-CoV-2.
While it can be used by anyone, the researchers underscore the difference the tests can make in the lives of patients with conditions that impair immune responses, such as cancer or use of immune-depressing drugs.
Detailed in an article published in the journal Cell Reports Methods, the test is still in the prototype phase. It uses the same technology as the rapid antigen test, which reveals the result on a card. However, in place of nasal discharge, users should collect a drop of blood from the finger.

Faced with the pandemic scenario and the expansion of the booster dose, some people still wonder what is the importance of the third dose of the vaccine against Covid-19stock

The booster dose should be administered at least four months after the individual completes the initial vaccination schedule. The extra application serves to increase the number of memory cells and further strengthen the antibodies they produce.Rafaela Felicciano / Metropolis

Specialists point out that one of the main measures provided by the booster dose is the expansion of the immune response. The third dose causes an increase in the amount of antibodies circulating in the body, which reduces the chance of the immunized person getting sick.Tomaz Silva/Agência Brasil

For the elderly and immunosuppressed, the booster dose increases the effectiveness of immunization, since these groups do not develop an adequate immune response.Hugo Barreto / Metropolis
Another important measure is to reduce the chance of infection in case of new variants. The antibody promoted by the vaccine is directed to the strain that gave rise to the formula and, in this process, people also produce antibodies that have diversity. The greater the reach of the proteins that defend the organism, the greater the probability that some will bind to the new variant.Westend61/GettyImages

A study conducted by the University Hospital Southampton NHS Foundation Trust in the UK showed that people who received two doses of AstraZeneca had a 30-fold increase in antibody levels after the Moderna vaccine booster, and a 25-fold increase with the booster of the vaccine. pfizerArthur Menescal/Special Metropolis

Reactions to the booster dose are similar to the two previous doses. Mild to moderate symptoms such as excessive tiredness and pain at the injection site are expected to occur. However, there are also reports of symptoms that include local redness or swelling, headache, muscle pain, chills, fever or nausea.Rafaela Felicciano / Metropolis
