Science Magazine: Covid vaccines may cause Long Covid–like symptoms

In November 2021, in the New England Journal of Medicine, William Murphy, an immunologist at the University of California, Davis proposed that an autoimmune mechanism triggered by the SARS-CoV-2 spike protein might explain both Long Covid symptoms and some rare vaccine side effects.… ...More...

EMA: Immune system could be overloaded by booster vaccinations

The European Medicines Agency warned this week that repeated booster shots are not a sustainable long-term plan. The EMA pointed out that getting a booster every four months could potentially result in diminishing someone’s immune response.… ...More...

Is Sars-CoV-2 already targeting the vaccinated?

Will future variants of Sars-Cov-2 tailor themselves to target the vaccinated?  Given that up to 90% of the population of some countries are now fully vaccinated, the question should perhaps be: Why would Sars-CoV-2 NOT target the vaccinated? … ...More...

Intravenous injection of mRNA Covid vaccine can induce acute myopericarditis in mice

This study provided in vivo evidence that inadvertent intravenous injection of COVID-19 mRNA vaccines may induce myopericarditis. Brief withdrawal of syringe plunger to exclude blood aspiration may be one possible way to reduce such risk.… ...More...

China continues with its Zero-Covid policy

Public health observers are confident that China’s “zero tolerance” COVID-19 policy will safeguard the country to withstand epidemic flare-ups, although the outbreak in East China’s Fujian Province is still intense and Northeast China’s Heilongjiang Province reported three fresh cases on Tuesday during the national holidays to mark the Mid-Autumn Festival.… ...More...

Preprint: MU B.1.621 the most resistant variant to convalescent and vaccinated sera to date

Here, we demonstrate that the Mu variant is highly resistant to sera from COVID-19 convalescents and BNT162b2-vaccinated individuals. Direct comparison of different SARS-CoV-2 spike proteins revealed that Mu spike is more resistant to serum-mediated neutralization than all other currently recognized variants of interest (VOI) and concern (VOC).… ...More...

Brazil: previously infected and fully vaccinated subjects with high anti-S IgG titers are susceptible to infection by VOC

Here we show that even previously infected and fully vaccinated subjects with high anti-S IgG titers are susceptible to infection by VOC, highlighting that immune responses induced by either natural infection or vaccination may not be sufficient to prevent infection by SARS-CoV-2 variants.… ...More...

Singapore: significant risk of vaccine breakthrough with the Sinovac #coronavirus vaccine

There is a significant risk of “vaccine breakthrough” with the Sinovac vaccine, or CoronaVac, with international evidence showing that many who had taken it were later infected with COVID-19, said the Ministry of Health’s (MOH) director of medical services Kenneth Mak on Friday, 18 June 2021.… ...More...
