免疫缺陷者接种疫苗有哪些注意事项？
What cautions apply when vaccinating immunocompromised people?
活疫苗对严重免疫缺陷者通常禁忌，因可能引发感染。灭活疫苗多可接种但应答可能较弱，需医生评估并个体化安排。接种前后应监测免疫状态和感染风险。
Live vaccines are usually contraindicated in severe immunodeficiency for infection risk. Inactivated vaccines are mostly fine but may respond weakly, needing individual assessment. Monitor immune status and infection risk around vaccination.

什么是同源接种与异源接种？
What are homologous and heterologous vaccination?
同源接种指各剂使用同一技术路线疫苗，异源接种则混合不同种类，如先灭活后蛋白亚单位。异源有时可激发更广或更强的免疫。具体方案由疾控根据证据制定。
Homologous vaccination uses the same platform for all doses; heterologous mixes types, like inactivated then protein subunit. Heterologous can sometimes broaden or strengthen immunity. Programs follow evidence-based public health plans.

老年人为什么是疫苗接种重点人群？
Why are older adults a priority group for vaccination?
免疫衰老使老人感染后重症和死亡风险更高，且疫苗应答偏弱。流感、肺炎球菌和带状疱疹疫苗对老人获益明确。接种前评估禁忌即可安全进行。
Immunosenescence raises older adults' risk of severe outcomes and weakens vaccine response. Flu, pneumococcal, and shingles vaccines clearly benefit them. With contraindication checks, vaccination is safe.

疫苗犹豫的主要成因有哪些？
What are the main drivers of vaccine hesitancy?
疫苗犹豫源于对安全性的担忧、错误信息、对机构的不信任和便利性问题。它不是单纯的拒绝，而是处在可改变的中间状态。针对性沟通和透明证据最为有效。
Vaccine hesitancy stems from safety worries, misinformation, distrust of institutions, and convenience. It is not outright refusal but a changeable middle state. Targeted communication and transparent evidence work best.

加强针的作用是什么？
What is the purpose of a booster shot?
随着时间推移，疫苗产生的抗体可能下降，加强针能重新激活免疫记忆、提升保护水平。在变异株流行或高危人群中被广泛采用。
Over time vaccine-induced antibodies may fall, and a booster re-activates immune memory and lifts protection. It is widely used during variant surges or for high-risk groups.

为什么有些人接种后没产生足够抗体？
Why do some people not make enough antibodies after vaccination?
年龄、免疫状态、营养和基因都可能影响抗体应答，老人和基础病患者反应常较弱。这并不意味着疫苗无效，仍多能提供一定保护。必要时可检测抗体水平。
Age, immune status, nutrition, and genetics affect antibody response; older and chronically ill people often respond weaker. It does not mean the vaccine fails, as partial protection still occurs. Antibody testing is sometimes used.

鸡蛋过敏能打流感疫苗吗？
Can someone with egg allergy get the flu vaccine?
多数现代流感疫苗卵蛋白含量极低，轻度鸡蛋过敏通常可以接种并在接种点观察。严重过敏史者需医生评估后决定。接种后留观是常规做法。
Most modern flu vaccines contain tiny egg protein, so mild egg allergy usually allows vaccination with observation at the site. A severe allergy history needs a doctor's assessment. Post-shot observation is routine.

mRNA疫苗和传统灭活疫苗原理有何不同？
How do mRNA vaccines differ from inactivated ones in principle?
灭活疫苗用被杀死的病原体直接提供抗原，mRNA 疫苗则让人体细胞暂读指令合成抗原。两者都训练免疫系统但不含活病毒。mRNA 技术便于快速更新应对变异株。
Inactivated vaccines use killed pathogens to supply antigen directly; mRNA vaccines make our cells briefly read instructions to build the antigen. Both train immunity without live virus. mRNA is easier to update for variants.

流感疫苗需要每年接种吗？
Do you need a flu vaccine every year?
流感病毒变异快，疫苗成分每年更新以匹配流行株，因此建议每年接种。接种后约两周产生保护力。高危人群尤其应接种。
Flu viruses mutate quickly and vaccine formulas are updated yearly to match circulating strains, so annual vaccination is advised. Protection builds about two weeks after the shot. High-risk groups especially should get it.

接种后胳膊疼正常吗？
Is a sore arm after vaccination normal?
接种部位疼痛、轻微红肿和低热是常见且正常的疫苗反应，通常一两天自行缓解。这属于免疫系统被激活的表现。持续高烧或严重不适应就医。
Soreness at the injection site, mild redness, and low fever are common, normal vaccine reactions that usually fade in a day or two. They show the immune system is being activated. Persistent high fever or severe symptoms need medical care.
