Progress and Pitfalls in the Quest for Effective SARS-CoV-2 (COVID-19) Vaccines.

There are currently around 200 SARS-CoV-2 candidate vaccines in preclinical and clinical trials throughout the world. The various candidates employ a range of vaccine strategies including some novel approaches. Currently, the goal is to prove that they are safe and immunogenic in humans (phase 1/2 studies) with several now advancing into phase 2 and 3 trials to demonstrate efficacy and gather comprehensive data on safety.

Non-typhoidal Salmonella infections in children: Review of literature and recommendations for management.

Non-typhoidal Salmonellae are a major cause of infectious diarrhoea worldwide and can cause invasive diseases, including bacteraemia, meningitis and osteomyelitis. Young or immunocompromised children and those with underlying conditions such as sickle cell disease are particularly vulnerable to invasive disease. There has been an increase in the rate of resistant non-typhoidal Salmonella, which is associated with invasive disease and hospitalisation.

Tetanus in New Zealand children: Intensive care management of a vaccine preventable disease.

Aim: To review management of children admitted with tetanus to Starship Children's Hospital from 2000 to 2013.

Methods: Retrospective chart review of children aged 0-15 years admitted to Starship Children's Hospital with tetanus from 2000 to 2013. Follow-up of immunisation status was via the National Immunisation Register and/or phone contact with patient's primary health care provider.
