COVID-19 stocks (vaccines and treatments)

Could one of these 22 health and biotech stocks be the gold mine of the decade?

The global race to find a COVID-19 cure might be over but with new variants continuing to emerge, vaccine makers are as relevant as ever.

With the arrival of the new BA.2.86 variant in August 2023 along with 9 other closely monitored variants by the World Health Organisation, global vaccine stocks are rising again.

We've put together a list of COVID vaccine stocks that emerged during the height of the 2020 pandemic. While not all of these stocks hit gold at the time, their research facilities may be central in the fight against new variants.

These are not recommendations, they are intended as investment ideas only.

1. Gilead Sciences, Inc. (NASDAQ: GILD)

Gilead is a biopharmaceutical company listed on the NASDAQ that researches, develops and produces new medicines for life-threatening illnesses.

Its stock price jumped in March after the US Food and Drug Administration (FDA) gave it the green light for funding towards one of its experimental drugs (and touted potential cure) Remdesivir. It's set to start enrolling test patients in March, with results out by May.

2. Atomo Diagnostics (ASX: AT1)

Atomo Diagnostics is an Australian medical device company working on the development and commercialisation of COVID-19 testing kits.

According the company, it pivoted from producing HIV testing kits – which requires a pin prick of blood and takes just 15 minutes for results to show – to COVID-19 kits once the pandemic struck. While still in talks with US and Australian healthcare companies, it has entered an agreement for the sale of 947,200 test kits to French diagnostics company NG Biotech.

The company also gets props as being part of Global Health Investment Fund portfolio headed by JPMorgan Chase & Co. and the Bill & Melinda Gates Foundation.
