Not saying there's any link - just that this is one to keep an eye on.

TT: The death of a two-month-old baby on Tuesday most likely was due to sudden infant death syndrome, rather than from drinking mother’s milk after the child’s mother got vaccinated against COVID-19 on Monday, doctors have said.

Responding to the mother’s speculation that the AstraZeneca vaccine had contaminated her breast milk, leading to the death of her child, (CECC's) Lee Ping-ing (李秉穎) said that no country in the world deems COVID-19 vaccines unsafe for breastfeeding mothers.

Yeah, if only we could trust the world health authorities to tell us the truth! That's the problem when you lied to us about human-to-human transmission, masks, airborne transmission, and the lab-leak - it's hard to believe you anymore.

Although no studies have been done with Covid vaccines, there is, according to this paper a suspected link between some vaccines and SIDS, especially the flu shot:

This study retrospectively investigated vaccination-related details and postmortem findings for 57 cases of sudden death in children 2 years or younger. Of the 32 cases in which any vaccines were administered, 7 infants (21.9%) had received immunization within 7 days of death. The most frequent vaccine cited as the last immunization before death was Haemophilus influenzae B.

(I)n 2011, 7 fatal incidents occurred in short order after combined immunization with Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae vaccines in Japan. Because some relation was suspected, vaccination was discontinued temporarily.

The paper also reports on two separate cases where twins died shortly after vaccinations were administered. If twins die suddenly - you've got to suspect some relationship with the vaccine.

WHO: SAGE does not recommend discontinuing breastfeeding after vaccination. More evidence is being sought in order to further inform WHO’s policy recommendations on this subject.
