The researchers found that neutralizing antibodies were over 70% even at the end of six months. While IgG showed an initial contraction but stabilised at relatively high levels over the…
The immune system elicits robust, broad and highly functional memory T cell responses once a person is infected with novel coronavirus. T cells were found even in the absence of…
Interim results of Phase-1 and Phase-2 trials of an inactivated SARS-CoV-2 vaccine carried out in China show that the vaccine is well tolerated, safe, and produced neutralizing antibodies at 14…
One more study has shown that pre-existing T cell memory against four common cold coronaviruses can cross-recognise novel coronavirus (SARS-CoV-2) even when the person has never been infected with SARS-CoV-2…
At least five studies found people unexposed to novel coronavirus exhibiting T cell immune responses specific to SARS-CoV-2. This might be arising from memory T cells derived from previous exposure…
The researchers found passive transfer of neutralising antibodies isolated from convalescent plasma into Syrian hamsters protect the animals against the disease when exposed to the virus and also protects hamsters…
The study found IgG levels and neutralizing antibodies started to decrease within two-three months after infection with novel coronavirus. The reduction was more (40%) in the case asymptomatic individuals than…
About 30% of patients with mild symptoms failed to develop high amounts of neutralising antibodies even after recovering from COVID-19 disease. If natural infection with novel coronavirus does not elicit…
