用疫苗筑起健康防护墙

Core Viewpoint - Vaccines serve as a crucial enhancement to the immune system, enabling the body to recognize and combat pathogens without experiencing actual infections [2] Group 1: Vaccine Mechanism - Vaccines provide the immune system with a "portrait of the enemy" (inactivated/attenuated vaccines), "weapon models" (recombinant protein vaccines), and "battle manuals" (mRNA vaccines) to prepare for future infections [2] - The immune system can quickly identify and eliminate pathogens upon actual exposure, often without the individual realizing they were infected [2] Group 2: Vaccine Achievements - The smallpox vaccine is noted as the only vaccine that has completely eradicated a disease [3] - The polio vaccine has made "infantile paralysis" a historical term [3] - The HPV vaccine is currently the only vaccine that can prevent cancer [3] Group 3: Common Questions about Vaccines - Vaccines significantly reduce the risk of severe illness and death, functioning more like "bulletproof vests" rather than infallible shields [3] - Common side effects such as localized redness and low fever indicate that the immune system is actively learning [4] - The occurrence of severe adverse reactions is much lower than risks associated with many daily activities [4] Group 4: Herd Immunity - Herd immunity occurs when a sufficient number of individuals are vaccinated, creating a "universal defense" that interrupts the transmission chain of the virus [5] Group 5: Parental Guidance - Parents are encouraged to ensure timely vaccinations for their children, as immunization is a free "shield" provided by the state [6] - It is important to maintain the "small green book" (Children's Vaccination Certificate) as it is essential for health records and school enrollment [6] - Parents should communicate their child's health status to healthcare providers before vaccination [6] - Post-vaccination care includes observing the child for 30 minutes and keeping the injection site clean [7] - Parents should seek authoritative information regarding vaccines from healthcare professionals rather than relying on online rumors [8]
