> The risk of spreading the Delta infection soon after vaccination with that jab was 42%, but increased to 58% with time.
42% (and even 58%) is still a huge improvement since the article says that the likelihood that an unvaccinated person will spread is around 67%.
The R0 value for Delta is between 6 and 7. So while an unvaccinated person might pass it on to ~6.7 people you will pass it on to only 4.2 people in the beginning (37% reduction), then to 5.8 people (13% reduction).
This calculation also assumes that your chance of getting Covid is the same as an unvaccinated person, which is not correct.
