COVID-19 Immunity after SARS-CoV-2 infections T cell responses probably play important roles in the control of SARS-CoV-2 infection, but they have been relatively understudied. Data now suggest that the majority of infected individuals develop robust and long-lasting T cell immunity, which has ...
Other factors also increase your vulnerability to reinfection, starting with how long it has been since you had Covid. Immune defenses tend to wane after an infection. A study published in October 2021 estimated that reinfection could occur as soon as 3 months after contracting Covid-19. While...
life-long) duration of immunity after clearing infection and no effect of cross-reactivity induced by other coronaviruses9. Even though there have been several reports of re-infection10, their numbers are negligible relative to the millions of reported infections...
development of herd immunity could also provide a defense against COVID-19. However, whether immunity occurs among individuals after they have recovered from COVID-19 is uncertain. Many human infections with other viral pathogens, such as influenza virus, do not produce a durable immune response....
Hybrid immunity provides better protection against COVID-19 than vaccination or prior natural infection alone. It induces high magnitude and broadly cross-reactive neutralising anti-Spike IgG antibodies. However, it is not clear how long these potent antibodies last, especially in the context of adeno...
Is large-scale vaccination sufficient for controlling the COVID-19 pandemic with uncertainties? A model-based study Abhijit Majumder Nandadulal Bairagi Nonlinear Dynamics (2024) Impact of sex and age on vaccine-related side effects and their progression after booster mRNA COVID-19 vaccine Masahik...
The goal of vaccination is to sufficiently prime the immune system against an infectious agent to prevent future disease. An effective vaccination program has proven to be critical in the fight against the COVID-19 pandemic, with the following four main methods leading the charge: mRNA vaccines,...
Where does that leave us as far as COVID-19 lockdowns are concerned? Those who oppose lockdowns should be glad to see that Sweden and many other places may soon be “COVID-free.” But invoking herd immunity as an explanation, persuasive as the biology may be, could be premature. Argu...
Interim results from the SIREN study suggest strong antibody protection after COVID-19, but reinfection risks remain.
