The Guardian: Israel says 600 children given Covid jab had no serious side-effects

Following an expansion of Israel's COVID-19 vaccination program, around 600 children (≥ 12 years) have received the Pfizer/BioNTech COVID-19 vaccine. Reported side-effects in this age group have been minor and the vaccine has been well tolerated.

Due to the emergence of more transmissible strains of COVID-19, experts have now suggested that in order to achieve herd immunity closer to 90% coverage will be required. In a population of 9 million people, with approximately 1/4 of those aged under 16 years, lowering the age limit for COVID-19 vaccination is an important development for Israel.

TGA: Vắc xin AstraZeneca ChAdOx1-S COVID-19

Denmark, Iceland and Norway have temporarily paused the distribution of COVID-19 AstraZeneca as a precautionary measure in response to reports of blood clots following immunisation (including 1 death in Denmark). The European Medicines Agency's safety committee is conducting a rapid review into the events.

The Therapeutic Goods Administration (TGA) have advised that a link has not been confirmed and to date there have been no reports of similar events in Australia. Extensive international vaccination programs have not indicated an increased risk of blood clots associated with the vaccine.

Vaccination with COVID-19 AstraZeneca continues in other countries including the United Kingdom and France.

Swollen Lymph Nodes Under Armpit After COVID-19 Vaccine May Mimic Breast Cancer Symptoms

The Society of Breast Imaging (SBI) in the United States is recommending women wait at least four weeks after receiving a COVID-19 vaccine to schedule a mammogram due to the potential side-effect of swollen or tender lymph nodes in the armpit. Changes in the lymph nodes can be a sign of breast cancer and the concerns are this could lead to false readings on mammograms leading to further unnecessary testing.

This advice was issued based on the rates of swelling and tenderness in the lymph nodes post the Moderna COVID-19 vaccine and Pfizer BioNTech COVID-19 vaccine in the United States. Whilst rare in people who have received the Pfizer BioNTech vaccine (which is currently provisionally registered for use in Australia), the SBI notes the incidence rates are most likely higher than reported and accordingly issued the aforementioned advice to separate mammograms from COVID-19 vaccines by four to six weeks.

ATAGI COVID-19 vaccination decision guide for women who are pregnant, breastfeeding or planning pregnancy

COVID-19 vaccines are not routinely recommended in pregnancy, however they are not contraindicated.

COVID-19 vaccines can be considered if a pregnant woman has medical risk factors for severe COVID-19 disease or is at a high risk of exposure and contact with people with the virus. Pregnant women have been shown to have an increased risk of needing admission to intensive care and requiring mechanical ventilation if they contract COVID-19 compared with non-pregnant women of the same age. Pregnant women can discuss this with their health provider to ascertain if the potential benefit of receiving a COVID vaccine outweighs any risks.

ATAGI have released a COVID-19 vaccination decision guide for women who are pregnant, breastfeeding or planning pregnancy and considering having a COVID-19 vaccine.
