Malaria vaccine clinical trials disappoint

motsoalediFinal clinical trials of a malaria vaccine – the first to reach this stage – tested on 16,000 children from seven African countries found that booster doses were of limited use and vaccines in young babies were not effective. They also found that meningitis occurred more frequently in children given the vaccine. Professor Brian Greenwood, study author and professor of the London School of Hygiene and Tropical Medicine, said he was 'a little disappointed'. 'I hoped the vaccine would be more effective, but we were never going to end up with the success seen in measles vaccines with 97% efficacy.' However, Greenwood said the data was very robust and the vaccine could still reduce attacks of malaria by around 30%.

No MMR-autism link, even in high-risk kids

A US study of approximately 95,000 children with older siblings found that receipt of the measles-mumps-rubella (MMR) vaccine was not associated with an increased risk of autism spectrum disorders (ASD), even among children already at higher risk for ASD. Although a substantial body of research over the last 15 years has found no link between the MMR vaccine and ASD, parents and others continue to associate the vaccine with ASD.

Kids’ self-control impacts health outcomes
