A Romanian-language Q&A-style video by Mihail Pautov answering common public questions about COVID-19 vaccines: herd immunity thresholds (minimum ~60%, ideal 70–80%), reasons some countries (Japan, Switzerland) delayed approvals, why pandemic vaccines were developed in under a year versus the usual 8–10 years, differences between Pfizer/Moderna/AstraZeneca and why choice is largely irrelevant, known side-effect incidences (injection-site pain ~84%, fatigue ~63%, headache/muscle pain ~50%), advice to avoid anti-inflammatories around vaccination, vaccine effectiveness (~95% with ~5% nonresponders), data on pregnancy/fertility (no effect observed in trials), and tentative duration of protection (antibody titers decline; possibly protective ~2 years if decline is linear). The speaker invites comments and emphasizes global equity concerns about vaccine distribution.

Questions this video answers

Minimum around 60%; ideal cited as 70–80%.

Injection-site pain ~84%; fatigue ~63%; headache and muscle pain ~50%.

About 95% efficacy; roughly 5% of vaccinated people may remain unprotected (one in 20).

Because Japanese law requires clinical trials conducted on Japan's population; Pfizer ran a separate trial in Japan after its U.S. study.

Over 500 million doses pre-ordered; population cited as approximately 126 million.
