Recent questions

  • What is the purpose of vaccines?

    Vaccines prime the immune system to rapidly respond to pathogens, preventing infection and increasing life expectancy by eradicating deadly diseases.

  • How do vaccines work in the body?

    Vaccines expose the immune system to particles that produce antibodies, recognizing and destroying pathogens to prevent infections and enhance immunity.

  • What are common concerns about vaccines?

    Chemophobia and vaccine hesitancy arise from worries about vaccine ingredients, fueled by past fraudulent studies linking vaccines to autism, despite their proven safety and efficacy.

  • Are COVID vaccines safe?

    COVID vaccines like Pfizer and Moderna's mRNA vaccines have undergone thorough clinical trials, ensuring safety, with medical professionals being early recipients, indicating their safety and efficacy.

  • Why is it important to wear masks?

    Wearing masks is crucial as they reduce pathogen transmission by 70%, primarily blocking aerosol droplets, showcasing minimal civic responsibility and aiding in preventing the spread of infectious diseases.

  • Thimerosal has been removed from most vaccines, with no change in autism diagnoses or prevalence.
  • Aluminum salts in vaccines are adjuvants that improve immune response, but the dose makes the poison.
  • Incidents like the 1955 polio immunization mishap and 1976 swine flu vaccine have fueled vaccine hesitancy.
  • Adverse reactions and vaccine injuries are possible, but the benefits of vaccines outweigh the risks.
  • COVID vaccines like Pfizer and Moderna's mRNA vaccines do not alter DNA and have been extensively researched.
