Modelling analysis reveals the burden of Japanese Encephalitis is greater than previously thought, and although vaccination has reduced burden, there are remaining places with a great need for vaccination.

Routine and campaign vaccination disruption in 2020 may lead to measles outbreaks and yellow fever burden increases in some countries, but is unlikely to greatly increase meningococcal A burden.

Vaccination activities that occurred before the COVID-19 pandemic, 2000-2019, are estimated to avert 50 million deaths, highlighting the enormous benefits of continued and improving vaccination.

Results from this modelled analysis indicate that short-term delays in HPV vaccination of adolescents are unlikely to have substantial long-term effects on HPV-related cancers, provided catch-up of missed vaccine doses can be implemented.

An individual-based model estimates exogenous boosting of immunity following re-exposure to chickenpox is limited to 2 years after re-exposure, but an increase in herpes zoster incidence is still expected to occur following universal varicella vaccination.

Natural transmission experiments should be prioritised over risky and expensive field trials, in order to establish the impact of cattle vaccination on the transmission of bovine Tuberculosis.

Yellow fever, a potentially deadly viral hemorrhagic fever, causes up to 82,000 deaths annually worldwide, and mass vaccination activities have reduced the burden by 47% in Africa.

Multi-model ensembling projected that the Delta variant would lead to a substantial COVID-19 resurgence in the US, with higher vaccination uptake being a critical factor for limiting transmission and impact between states.

Offering measles vaccination to parents who bring their children to receive any dose of measles vaccine can accelerate measles elimination in Italy.

Social networks can be the primary risk factor for mumps infection and transmission, regardless of age and vaccination status.
