Scientists uncovered the structure of the key protein for a future hepatitis C vaccine – here’s how they did it

Using a Nobel Prize-winning technique called cryo-EM, researchers were able to identify potential areas on the hepatitis C virus that a vaccine could target.

Inhaled vaccine for COVID-19: The pandemic accelerated decades of research leading to jab-free vaccine now in human testing

An inhaled COVID-19 vaccine would go directly to where the body would use it: the mucosal surface of the airways. This could mean less waste and more benefit, lower costs and reduced side-effects.

International Statistic of the Year: Race for a COVID-19 vaccine

The coronavirus vaccine was developed faster than any vaccine in history. It took just 332 days from the first sequencing of the virus genome to the first vaccines given to the public.
The pharmaceutical industry opposes the suspension of intellectual property rights on COVID-19 vaccines and treatments, and no pharma companies have yet contributed to the COVID-19 Technology Access Pool. (Shutterstock)

Can a pharma company change? Profit, not altruism, motivates COVID-19 vaccine development

We should applaud drug companies for developing COVID-19 vaccines in record time, but let’s not be under any illusion about the profits that are motivating them.

The mink link: How COVID-19 mutations in animals affect human health and vaccine effectiveness

In the disturbing scenario of human-to-mink-to-human COVID-19 transmission, the virus may mutate in mink prior to re-infecting people. That possibility makes vaccine design even more crucial.
