The UK could carry out Covid ‘challenge trials’, where healthy volunteers are deliberately infected with coronavirus to test possible vaccines. Challenge studies were used to test vaccines for flu, cholera and typhoid, but there were treatments to prevent volunteers from falling ill. Coronavirus trials have the added risk that should volunteers become unwell, the only drugs available will control the disease not remove it. University student Alastair Fraser-Urquhart will volunteer if the trial goes ahead. He said, ‘I think it might save thousands of lives and bring the world out of the pandemic sooner.’ Professor Peter Horby said the trials have the potential to advance science and help us to better understand coronavirus. ‘The risk in a healthy young adult with no underlying conditions is extremely low. What's been holding things up are ethical considerations.’

The flu season has started early this year. Doctors are predicting a rise in cases, with hundreds of thousands possibly having Christmas ruined by flu. GP consultations for flu-like illness were up by a quarter to 7,500 visits in the week ending 8 December. Grandparents visiting grandchildren could be particularly at risk. Children are ‘super-spreaders’ of flu, and the elderly can develop complications if they catch it. While more over-65s are having a free flu jab this year, coverage among two- to three-year-olds is lagging behind previous seasons, following delivery delays of nasal flu vaccine. These have now been resolved, but some school flu programmes will not begin until January. Experts are urging anyone who has not yet had their vaccination to do so.

An exceptional measles epidemic in Samoa is attributed to a decision in 2018 to suspend  a vaccination programme after two infants died following vaccination. UNICEF has now sent Samoa 110,500 vaccines, and the government has issued extreme measures to secure ‘public safety’ as the crisis worsens. No vehicle is permitted on the road unless it belongs to an exempt service from the public sector or is being used to seek medical assistance from a medical facility. All inter-island travel between Upolu and Savaii is prohibited, except to get medical assistance. Everyone must stay at home to await the vaccination units being mobilised for the MMR vaccination plan. Public sector services exempt from closure include hospitals, morgues, fire and emergency services, police, search and rescue, and security. But people continue to avoid vaccinations, even as the country is shut down under strict emergency laws, in part due to high-profile foreign interference.

A government campaign to vaccinate 40 million children under the age of five against polio had to be suspended following serious attacks on workers and police in just one week. A policeman protecting polio workers was killed in Bannu, and a polio worker was injured with a knife in Lahore by a man refusing to allow his child to be vaccinated. Two others connected with different polio teams were also killed, and one man was seriously wounded. Further attacks on staff in Sindh, Balochistan and Punjab were reported. The violence was preceded by a series of rumours intended to derail Pakistan’s campaign to eradicate the disease. On 22 April several thousand children were taken to hospital in north-west Pakistan by panicked parents after a video circulated on Facebook in which a man attested that children were falling sick following vaccinations. A mob set alight a health centre following the same rumour.
