If a virus is disease-causing, the right mutation can allow the virus to escape the immuneresponse by changing the viral pieces the immune system uses to recognize the virus as a threat, pieces scientists call epitopes.
The outcome confirms that only one single case was attributable to the original SARS-CoV-2 virus. “In addition, the variant-rich environment underlines the importance of developing next-generation vaccines as new virus variants continue to emerge.” More than half of the cases (57%) were caused by Variants of Concern.
Currently in Phase 3 clinical testing in the United Kingdom for the prevention of COVID-19, NVX-CoV2373 is a recombinant protein vaccine adjuvanted with Novavax’ proprietary Matrix-M to enhance the immuneresponse. The company will work with Medsafe, New Zealand’s regulatory agency, to obtain product approvals as needed. About Novavax.

Type: Adenovirus-based.
Clinical trial to assess safety, immuneresponse and reactogenicity, after preclinical data showed high neutralizing antibody levels. Expected to enroll 415 participants; interim results expected in Q3 2021. The Companies expect interim results from this trial in the third quarter of 2021. About Translate Bio.
A trial of a new vaccine that appears to train the immune system to fight coronavirus has begun in the UK. Early tests showed the jab, developed by US biotechnology company Novavax, leads to high levels of virus-fighting antibodies being produced. The trial on 10,000 people will now see if the vaccine can prevent people getting ill.
Depending on the overall COVID-19 attack rate, interim data in the UK trial, which is also event-driven, are expected as soon as early first quarter 2021. NVX-CoV2373 is a vaccine candidate engineered from the genetic sequence of SARS-CoV-2, the virus that causes COVID-19 disease. About NVX-CoV2373.
15, 2021 (American Heart Association News) — Experts have a simple answer for heart and stroke patients questioning whether they need a COVID-19 vaccination. Vardeny, who has done extensive research on flu vaccines, said such reactions are a sign the body is developing an immuneresponse, “and that’s a good thing.
“We continue to see the strongest effects in patients who are most at risk for poor outcomes due to high viral load, ineffective antibody immuneresponse at baseline, or pre-existing risk factors. In the overall patient group with detectable virus at baseline, the average daily reduction in viral load through day 7 was a 0.36

The study also found mice immunized with a SARS-CoV-1 vaccine developed in 2004 generated immuneresponses that protected them from intranasal exposure by SARS-CoV-2. Cross-protective immunity following coronavirus vaccination and coronavirus infection.
Many of the elderly patients who survived the virus were poor: not exactly the demographic you would expect to fare well in a health crisis. One of the most dangerous phenomena COVID-19 can trigger in your body is something called a cytokine storm, which is a potentially fatal amplification of an immuneresponse.
Patrick Soon-Shiong MD, chairman and CEO of ImmunityBio, said: “There is an urgent need for a vaccine that not only offers immediate protection but also activates T cells to clear the virus. When multiple mutations occur at the receptor-binding domain of the spike protein, it renders antibodies ineffective.
