Moderna: COVID-19 Vaccine Phase 2/3 Study in Children 6 Months to ≤ 6 Years successfully meets its primary endpoint

Moderna has announced interim data from the Phase 2/3 KidCOVE COVID-19 vaccine study ahead of its submission to global regulatory bodies.

Approximately ​4,200 children aged 2 to <6 years and 2,500 children aged 6 months to <2 years were recruited across the U.S. and Canada ​with participants receiving 2 doses of 25 μg, 28 days apart (a lower dose compared with older age groups).

Moderna reports immunogenicity consistent with that seen in adults (18-25 years) receiving doses of 100mcg with a vaccine efficacy of 43.7% in those aged 6 months to <2 years and 37.5% in those aged 2 to <6 years.  Omicron was the predominant COVID-19 strain circulating during this trial.

Adverse events following vaccination were reported as mild or moderate and more frequently ​associated with dose two. No deaths, myocarditis, pericarditis, ​or cases of multisystem inflammatory syndrome in children (MIS-C) were reported. ​Independent safety monitoring ​will continue for 12 months following the second dose.

ATAGI clinical guidance on Japanese encephalitis virus vaccines

ATAGI have released new guidance for healthcare providers ​regarding the administration of Japanese encephalitis virus (JEV) vaccines.​ These recommendations follow on from earlier advice from CDNA identifying the groups at highest risk of disease and who should be prioritised for vaccination.

The guidance includes:

  • vaccine brand and dosing recommendations
  • priority populations
  • advice for women who are pregnant or breastfeeding
  • booster doses
  • co-administration with other vaccines
  • ​common and expected side effects following vaccination

ATAGI statement on recommendations on a winter booster dose of COVID-19 vaccine

As part of winter preparedness, ATAGI have provided recommendations for an additional COVID-19 vaccine winter booster dose for select groups who have been identified as being at highest risk of severe COVID-19 disease. These groups include: 

  • individuals aged ≥ 65 years   
  • residents of aged care or disability care facilities  
  • individuals aged ≥ 16 years with severe immunocompromise 
  • Aboriginal and Torres Strait Islander people aged ≥ 50 years. 

The rollout of winter booster doses will commence from April in line with the 2022 influenza vaccination program, with both vaccines able to be co-administered where appropriate. Winter booster doses of COVID-19 vaccines can be administered from ≥ 4 months since the previous booster dose/confirmed SARS-CoV-2 infection (whichever is later).

mRNA vaccines (Comirnaty (Pfizer) or Spikevax (Moderna)) remain the recommended brands for use as booster doses, with Vaxzevria (AstraZeneca) available for those who have a contraindication to mRNA vaccines. Nuvaxovid (Novavax) may be used in circumstances where no other vaccine brand is deemed suitable.

ATAGI suggests that there is currently insufficient evidence at this time to support a recommendation for additional boosters for other individuals. For these groups, protection from a primary course of COVID-19 vaccine followed by 1 booster dose continues to provide good protection against hospitalisation with COVID-19 disease. Further recommendations may be considered in the future as more evidence emerges.

Vocal cord dysfunction/inducible laryngeal obstruction(s) mimicking anaphylaxis during SARS-CoV-2 (COVID-19) vaccination

Researchers at Monash Health have published findings related to vocal cord dysfunction/inducible laryngeal obstruction(s) (VCD/ILO) in relation to incident-associated VCD which may be related to vaccination.

Their findings are related to a case series of ten individuals who were initially labelled as having experienced anaphylaxis following COVID-19 vaccination. These individuals were referred on to a specialist allergy service, where 9 out of the 10 received a second dose of the same COVID-19 vaccine that caused their initial reaction.  It was found that 2 out of the 10 individuals met the Brighton Criteria for anaphylaxis, and symptoms recurred in 8 of the 9 individuals who received a second dose, mirroring their initial reactions which had been diagnosed as anaphylaxis.

Clinical features of VCD/ILO overlap with those of the Brighton Criteria for vaccine-related anaphylaxis, with this research demonstrating the need for providers to be able to differentiate between anaphylaxis and VCD/ILO.

The New York Times: In Africa, a Mix of Shots Drives an Uncertain Covid Vaccination Push

While many wealthy countries are well on track with their COVID-19 booster rollout using the Pfizer and Moderna vaccines, African countries continue to rely on products and dosing schedules that many researchers believe render lower vaccine efficacy.  

With COVID vaccination rates averaging about 14% across the continent, experts reveal that there are several barriers to vaccination to consider and warn that a fifth, potentially more lethal wave is imminent.
