Novavax’s COVID-19 vaccine shows efficacy of 90.4% in clinical trials


Vaccine maker Novavax on Monday claimed that its COVID-10 vaccine candidate has an overall efficacy of 90.4 per cent. The results are based on the phase 3 trials conducted on 29,960 participants across 119 sites in the US and Mexico.

Notably, the company intends to touch a manufacturing capacity of 100 million doses per month by the end of the third quarter and subsequently, increase the capacity to 150 million doses per month by Q4 of 2021. The company said that it plans to apply for regulatory authorisations in Q3, after completion of the final phases of necessary checks.

The study

The study was conducted on people aged 18 and above in the US and Mexico. Two-thirds received two doses of the vaccine, three weeks apart, and the rest got dummy shots.

There were 77 cases of COVID-19— 14 in the group that got the vaccine and the rest were in volunteers who received dummy shots. None in the vaccine group had moderate or severe disease, compared to 14 in the placebo group.

The vaccine was similarly effective against several variants including the one first detected in the UK that is dominant in the US, and in high-risk populations including the elderly and people with other health problems.

Side-effects of the vaccine

Side effects were mostly mild tenderness and pain at the injection site, with the pain lasting for less than three days. Fatigue, headache and muscle pain were the most common systemic symptoms, lasting less than 2 days. There were no reports of unusual blood clots or heart problems.

SII to also rollout Novavax vaccine

Pune-based Serum Institute of India, which is already manufacturing Covishield, will also manufacture the vaccine developed by Novavax. However, its rollout in India is likely to happen only after regulatory clearances from the Indian authorities and after the parent company launches the vaccine.
