When a Covid-19 vaccine is discovered, will it be freely available and be affordable to all? The global intellectual property system allocates the rights of the vaccine to the inventor or owner. These rights are granted for a limited period – 14 years in the US and the European Union, 20 years in most other places. During this time, the owner has a monopoly over the product and can demand a price they seem fit. However, this provision has often been used by the inventors to limit access to essential goods to people who need them or to smaller companies that could manufacture the product at affordable prices. Read here to understand whether the Covid-19 vaccine will become freely available and be affordable. 

Sending the right message: Communicating science means explaining details to the public without condescension, admitting mistakes, promptly rebutting pseudo-science, being guided by data and interpreting the logic for policies undertaken. Instructions provided by scientists may be inconvenient and fail to take note of election cycles. Even when the situation is long-drawn-out, as in the Covid-19 pandemic, listening to scientists and putting their advice into practice can lead to better management of the pandemic, as seen in New Zealand and some Southeast Asian countries.

As lockdown squeezes grey market, families struggle to import life-saving drugs: India’s lockdown, which began on March 25, hit the imports of all pharmaceuticals. With no new stock coming in, both patients and grey market vendors started running out of vigabatrin. Whatever residual stock remained with Indian vendors started getting sold at marked-up prices. So, Indian patients have begun to individually import small consignments into the country, though this is expensive for many and has put a vital medicine out of their reach.

Understanding Covid-19

How effective are the drugs approved to treat Covid-19 patients in India? The Central Drugs Standard Control Organisation (CDSCO) has approved five drugs in the last month for Covid-19 treatment – two antiviral: Remdesivir and Favipiravir – and three for easing the symptoms: Dexamethasone, Tocilizumab and Itolizumab. These drugs’ use is bound to birth complications considering there are doubts about the evidence the government has furnished – or not – to approve their use. Read more here.

 
Aerosols are a bigger coronavirus threat than WHO guidelines suggest: When someone coughs, talks or even breathes, they send tiny respiratory droplets into the surrounding air. The smallest of these droplets can float for hours, and there is strong evidence that they can carry live coronavirus if the person is infected. Aerosol concentrations can be reduced with increased ventilation, although recirculating the same air should be avoided unless the air can be effectively filtered prior to reuse. When possible, open doors and windows to increase fresh air flow. Read more here

How immunity is developed: A longitudinal study by the researchers from King’s College London — first reported by The Guardian on Sunday — has suggested that immunity to Covid-19 might be lost in months. The suggestion is based on a steep drop in patients’ antibody levels three months after the infection. A look at the findings, implications and limitations of the new study, and the broader question of how the body develops immunity against an infection. Read more here
