vito, мы говорим не о "цене", а о возможности.
Замечено, что наиболее крупные среди известных пандемий в истории человечества (унесшие больше жизней, чем ковид) -
все (кроме бубонной чумы) заканчивались за 2-3 года.
Из них - только последние две (Asian flu' 1957–1958,
Hong Kong flu 1968–1970) - коллективный иммунитет с вакцинацией (унесли 0.1% популяции)
Остальные уносили до 40-60% популяции, но зато коллективный иммунитет без вакцинации.
Plague of Justinian (beginning of 1st plague) 541–542 Europe and West Asia Bubonic plague 30–50 million (40–50% of Europe)
Black Death (start of the Second plague) 1346–1353 Europe, Asia and North Africa Bubonic plague 75–200 million (10–60% of European)
1520 Mexico smallpox 1519–1520 Mexico Smallpox 5–8 million (40% of popul.)
Cocoliztli of 1545–1548 1545–1548 Mexico Possibly Salmonella enterica 5–15 million (80% of popul.)
Third plague 1855–1960 Worldwide Bubonic plague 12 million+
1918 influenza ('Spanish flu') 1918–1920 Worldwide Influenza A virus subtype H1N1 50(17–100 million) (3–5% world's)
1957–1958 influenza ('Asian flu') 1957–1958 Worldwide Influenza A virus subtype H2N2 1–4 million
Hong Kong flu 1968–1970 Worldwide (mainly in Hong Kong) Influenza A virus subtype H3N2 1–4 million

Учитывая то, что локдаунов и карантинов 100 лет назад толком не вводили
Вообще-то, карантины, соц. дистанцирование, маски - это было в некоторой степени во времена influenza ('Spanish flu') 1918–1920:
Maritime quarantines were declared on islands such as Iceland, Australia, and American Samoa, saving many lives. Social distancing measures were introduced, for example closing schools, theatres, and places of worship, limiting public transportation, and banning mass gatherings. Wearing face masks became common in some places, such as Japan, though there were debates over their efficacy. There was also some resistance to their use, as exemplified by the Anti-Mask League of San Francisco. The actual enforcement of various restrictions varied.To a large extent, the New York City health commissioner ordered businesses to open and close on staggered shifts to avoid overcrowding on the subways.
A later study found that measures such as banning mass gatherings and requiring the wearing of face masks could cut the death rate up to 50 percent, but this was dependent on their being imposed early in the outbreak and not being lifted prematurely
There were also differences between cities, which might have reflected exposure to the milder first wave giving immunity, as well as the introduction of social distancing measures.
1918 Chicago newspaper headlines reflect mitigation strategies such as increased ventilation, arrests for not wearing face masks, sequenced inoculations, limitations on crowd size, selective closing of businesses, curfews, and lockdowns.[ After October's strict containment measures showed some success, Armistice Day celebrations in November and relaxed attitudes by Thanksgiving caused a resurgence.

антибиотиков не было
антибиотики лечат только бактериальные инфекции.
антибиотики НЕ лечат только вирусные инфекции (flu, covid)
