1. 如果我係pathogen入侵既頭個幾日睇醫生係米咩都check唔到?

2. 打booster 既antibody數量係米比sencondary response 更多更耐?

3. vaccine 點解made of similar pathogen 唔係same pathogen 都可以殺到比較勁既actual pathogen?

4.passive immunity個度 ,prepared antibody 通常加埋antigen打入體內去remember個pathogen ,但係 antibody 同antigen會打埋一齊 ,
   咁仲點殺個pathogen?

thx!

1. 如果我係pathogen入侵既頭個幾日睇醫生係米咩都check唔到?
醫學check唔check到唔到我地泥鑑證
pathogen岩岩入幾日,個「身體」可能detect唔到,因為個個amount仲未好多
reproduction of bateria/virus仲未太勁
2. 打booster 既antibody數量係米比sencondary response 更多更耐?
打booster係為左做一個addition of antibodies.
咁你d antibody(例如一出生打個d)
都會gradually咁消失嫁
唔通一世係你身體咁正咩
booster以我記憶同問人,好似係做addition的
做補充的.secondary response更耐,應該可以咁講
3. vaccine 點解made of similar pathogen 唔係same pathogen 都可以殺到比較勁既actual pathogen?
Vaccine係made up by dead /weakened pathogen,,正常應該係同種嫁bo,邊度say similar?
打落去係為左製作primary response,下次再有same 品種既pathogen,就stimulate個secondary response
4.passive immunity個度 ,prepared antibody 通常加埋antigen打入體內去remember個pathogen ,但係 antibody 同antigen會打埋一齊 ,
   咁仲點殺個pathogen?
好似唔會加antigen嫁bo=.=
thx!

2.打booster係令身體快d產生secondary response(令個memory cell既記憶更長)
3.就算係made of similar pathogen,但佢個antigen都係無變.lymphocyte會變成memory cell remember個pathogen既antigen

其實我bio讀中文,可能有d打錯

1.咁係米check唔到?
2.打太多booster有無後果?
4.passive immunity係打antibody
  例如你俾隻狗咬左有瘋狗症 ,瘋狗症未到secondary response你已經死
  你要搵返個隻狗拎antibodies 射入你到先唔死

1.睇下你咩pathogen,好似AIDS個d有潛伏期咪check唔到
4,之前唔知咩係passive immunity
passive immunity姐係打血清~

咁係米in excess?
amount : antigen > antibody > pathogen?

咁我又唔係好清楚,我岩岩先教到呢課,仲未教完

打疫苗針 只係會打antigens 唔會打antibodies
